This provides support for building SBOMs in CycloneDX format.
A target is added alongside the other reports, that (based on the
fast-bsp-report) extracts name, version, cpe and license of each target
package, and puts these into a final sbom-report in CycloneDX/JSON
format.
This requires a working Python3 setup with the cyclonedx-bom package
installed.
