Non-hierarchical merge with dependency (or at least unified)

I tried with hierarchical and non-hierarchical merging on two layers of SBOMs. While hierarchical would achieve what I want, it massively increase the amount of components and dependencies by adding lots of duplication whereas non-hierarchical nicely merges the dependencies but is not adding the `dependsOn` for each `metadata.component` as the hierarchical does.

Is there any way to get nicely merged SBOMs with dependency without this duplication? My structure that I need (all coming from single SBOMs) looks like this:

* main.cdx.json (merged)
* project1.cdx.json (merged)
* subproject1.cdx.json
* subproject2.cdx.json
* subproject3.cdx.json
* subproject4.cdx.json
* project2.cdx.json
* project3.cdx.json
* project4.cdx.json
* project5.cdx.json
* project6.cdx.json

Without the `--hierarchical` I sadly don't have a nice way to simply add the (which is the only thing I miss on the call without the flag):
```json
{
"ref": "project1@version1",
"dependsOn": [
"subproject1@version1",
"subproject2@version1",
"subproject3@version1",
"subproject4@version1"
]
},
{
"ref": "main@version",
"dependsOn": [
"project1@version1",
"project2@version2",
"project3@version3",
"project4@version4",
"project5@version5",
"project6@version6"
]
}
```

Without this, DepdendencyTrack won't be able to pick up the dependency tree and also logically it would be missing in my use-case. Doing `--hierarhical` currently creates the dependencies like this (not even speaking about the components):
```json
[
{
"ref": "project1@version1:subproject1@version1:subproject1@version1",
"dependsOn": [
"project1@version1:subproject1@version1:pkg:nuget/Aspire.MongoDB.Driver@13.1.1",

"project1@version1:subproject1@version1:pkg:nuget/Serilog.Sinks.Async@2.1.0",
"project1@version1:subproject1@version1:pkg:nuget/Serilog.Sinks.Grafana.Loki@8.3.2",
"project1@version1:subproject1@version1:pkg:nuget/Serilog.Sinks.OpenTelemetry@4.2.0"
]
},
{
"ref": "project1@version1:subproject2@version1:subproject2@version1",
"dependsOn": [
"project1@version1:subproject2@version1:pkg:nuget/Aspire.MongoDB.Driver@13.1.1",
"project1@version1:subproject2@version1:pkg:nuget/Serilog@4.3.0",

"project1@version1:subproject2@version1:pkg:nuget/Serilog.Sinks.Async@2.1.0",
"project1@version1:subproject2@version1:pkg:nuget/Serilog.Sinks.Grafana.Loki@8.3.2",
"project1@version1:subproject2@version1:pkg:nuget/Serilog.Sinks.OpenTelemetry@4.2.0"
]
},
{
"ref": "project1@version1:subproject3@version1:subproject3@version1",
"dependsOn": [
"project1@version1:subproject3@version1:pkg:nuget/Aspire.MongoDB.Driver@13.1.1",
"project1@version1:subproject3@version1:pkg:nuget/Serilog@4.3.0",
"project1@version1:subproject3@version1:pkg:nuget/Serilog.AspNetCore@10.0.0",
"project1@version1:subproject3@version1:pkg:nuget/Serilog.Enrichers.Span@3.1.0",
"project1@version1:subproject3@version1:pkg:nuget/Serilog.Exceptions@8.4.0",
"project1@version1:subproject3@version1:pkg:nuget/Serilog.Sinks.Async@2.1.0",
"project1@version1:subproject3@version1:pkg:nuget/Serilog.Sinks.Grafana.Loki@8.3.2",
"project1@version1:subproject3@version1:pkg:nuget/Serilog.Sinks.OpenTelemetry@4.2.0"
]
},
{
"ref": "project1@version1:project1@version1",
"dependsOn": [
"project1@version1:subproject1@version1:subproject1@version1",
"project1@version1:subproject2@version1:subproject2@version1",
"project1@version1:subproject3@version1:subproject3@version1",
"project1@version1:subproject4@version1:subproject4@version1"
]
},
{
"ref": "main@version",
"dependsOn": [
"project1@version1:project1@version1",
"project2@version2:project2@version2",
"project3@version3:project3@version3",
"project4@version4:project4@version4",
"project5@version5:project5@version5",
"project6@version6:project6@version6"
]
}
]
```

In cases where all components are exactly the same, I would love to see them merged before export to something like this:
```json
[
{
"ref": "subproject1@version1",
"dependsOn": [
"pkg:nuget/Aspire.MongoDB.Driver@13.1.1",
"pkg:nuget/Serilog@4.3.0",
"pkg:nuget/Serilog.AspNetCore@10.0.0",
"pkg:nuget/Serilog.Enrichers.Span@3.1.0",
"pkg:nuget/Serilog.Exceptions@8.4.0",
"pkg:nuget/Serilog.Sinks.Async@2.1.0",
"pkg:nuget/Serilog.Sinks.Grafana.Loki@8.3.2",
"pkg:nuget/Serilog.Sinks.OpenTelemetry@4.2.0"
]
},
{
"ref": "subproject2@version1",
"dependsOn": [
"pkg:nuget/Aspire.MongoDB.Driver@13.1.1",
"pkg:nuget/Serilog@4.3.0",
"pkg:nuget/Serilog.AspNetCore@10.0.0",
"pkg:nuget/Serilog.Enrichers.Span@3.1.0",
"pkg:nuget/Serilog.Exceptions@8.4.0",
"pkg:nuget/Serilog.Sinks.Async@2.1.0",
"pkg:nuget/Serilog.Sinks.Grafana.Loki@8.3.2",
"pkg:nuget/Serilog.Sinks.OpenTelemetry@4.2.0"
]
},
{
"ref": "subproject3@version1",
"dependsOn": [
"pkg:nuget/Aspire.MongoDB.Driver@13.1.1",
"pkg:nuget/Serilog@4.3.0",
"pkg:nuget/Serilog.AspNetCore@10.0.0",
"pkg:nuget/Serilog.Enrichers.Span@3.1.0",
"pkg:nuget/Serilog.Exceptions@8.4.0",
"pkg:nuget/Serilog.Sinks.Async@2.1.0",
"pkg:nuget/Serilog.Sinks.Grafana.Loki@8.3.2",
"pkg:nuget/Serilog.Sinks.OpenTelemetry@4.2.0"
]
},
{
"ref": "project1@version1",
"dependsOn": [
"subproject1@version1",
"subproject2@version1",
"subproject3@version1",
"subproject4@version1"
]
},
{
"ref": "main@version",
"dependsOn": [
"project1@version1",
"project2@version2",
"project3@version3",
"project4@version4",
"project5@version5",
"project6@version6"
]
}
]
```

It's fine to keep `project1@version1:` prefixes if name conflicts are found, but duplicating ALL components for no reason is not what I expect.
