Load Metadata Component Values like Description, CPE, PURL and Properties into Project

### Current Behavior

Metadata values in the sbom don't get imported.

```
"metadata": {
"component": {
"type": "file",
"name": "ignored",
"description": "text not imported",
"cpe": "cpe:2.3:a:my-project:not-imported-either:1.2.FR:*:*:*:*:*:*:*",
"purl": "pkg:maven/my-project/not-imported-either@1.2.FR",
"pedigree": {
"commits": [ {
"url": "https://myurl"
}
]
},
"properties": [ {
"name": "my-value",
"value": "https://myurl"
}
]
}
},
```

### Proposed Behavior

Description, Properties, CPE, PURL should all be imported into the project if valued.
