Extend cycloneDX presenters with syft-specific values #154
Description
The CycloneDX spec allows for user-defined values to be added to most select sections. We should extend each component to report out grype-specific information. Similar to our json output, but embedded in each component section:
<syft:metadata version="1">
<catalogers>
<cataloger>python-cataloger</cataloger>
</catalogers>
<locations>
<location>
<path>/somewhere/to-path.json</path>
<layer-index>1</layer-index>
</location>
</locations>
</syft:metadata>
