Packaging for Debian Trixie

[Urist-McGit]

There are some outstanding issues in the code that would prevent a direct packaging as outlined here.

The following problems are currently known:

• cyclonedx-python-lib is required to be >= 11.0.0, whereas the version in trixie is 9.1.0-2 (resolved by Dependency cleanup #139)
• spdx-tools is currently only available in forky and sid, and not in trixie (partially resolved by Refactor/optional SBOM dependencies #134)
• beartype version 0.20.0 is available in trixie, we require 0.21.0 because of the use of FrozenDict in our tests (resolved by Replace typing.IO type hints #138)
• trixie uses sphinx version 8.1.3-5 while the pyproject.toml specifies sphinx>=7,<8 (resolved by Dependency cleanup #139)

With the current state in the main branch we are able to package for trixie, but only with the CDX format. The only blocker for a complete packaging is the spdx-tools lib, which has found its way into unstable.

Just for reference / to track this here, once #155 and #156 are merged, #157 should contain everything you need in order to build both binary and source packages of debsbom, minus the debian/changelog file.

python3-spdx-tools is not yet included as a dependency as of writing this, but can always be added later on / at your discretion, of course.

The package is now available in Debian testing. If desired, we can also provide a backport for trixie. By that, I'll close the issue. Thanks to all involved people for the excellent collaboration.
