Make `cyclonedx-maven-plugin` work together with `frontend-maven-plugin`

I use `cyclonedx-maven-plugin` to generate SBOM for my multi-module maven project.

Some of my maven module contains a jetty server + a frontend managed with npm, the frontend-build process is execute during the maven build thanks to [`frontend-maven-plugin`](https://github.com/eirslett/frontend-maven-plugin).

The frontend build also generate sbom thanks to [cyclonedx-node-npm](https://github.com/CycloneDX/cyclonedx-node-npm). I'm able to generate this frontend SBOM in corresponding maven`${project.build.directory}`.

So now ideally, I would like that this bom can be taking into account by `cyclonedx-maven-plugin`.
Maybe by aggregate it to sbom of the corresponding maven module ?

1) Do you think this could be in the scope of this project ?
2) Do you think this make sense to aggregate the frontend SBOM with the maven SBOM when using `makeBom` goal ? or should it be 2 seperated BOM ?
3) Do you think this make sense to aggregate the SBOM with `makeAggregateBom` goal ?
4) Or do you see better way to make this works together ?

I think this is related to : https://github.com/CycloneDX/cyclonedx-maven-plugin/issues/395

If you want to include this in `cyclonedx-maven-plugin` I can help. Let me know :pray:

Start with issue #395 and the existing makeBom and makeAggregateBom entry points, then review how frontend-maven-plugin and cyclonedx-node-npm produce SBOMs in the Maven build directory. Define the intended aggregation behavior and acceptance criteria for both goals before identifying implementation and test locations.
