`cyclonedx-py` fails with `poetry` v1.3 due to new v2 lock format

[tewfik-ghariani]

Starting poetry v1.3, the lock file format has changed essentially in the part of specifying the files/hashes per package instead of a dedicated metadata.files

lock v1

lock v2

Refs: python-poetry/poetry#6393

As a result, the cyclonedx-py tool is no longer able to generate the bom file because it cannot parse the new format

$ cyclonedx-py --poetry -o target/bom.xml

thanks for the report and the RP #468.
I will look into it ASAP.

[jkowalleck]

should be fixed via 3.10.0.

could you test and confirm, @tewfik-ghariani ?

@jkowalleck Works like a charm, thanks a lot! 🎉
