currently, we "fix" licenses

this is no longer needed since CycloneDX 1.7

feature request: dont "fix" licenses if not needed.

this might be considered a breaking change, since the output result might be different.

Start with cyclonedx_py/_internal/utils/cdx.py around lines 102-119 and read the linked CycloneDX issues and specification context. Determine how CycloneDX 1.7 changes the license requirement, then verify that licenses are left unchanged when the compatibility fix is unnecessary. The completed change should account for the possible output change noted in the issue.
