zstd support in python-debian

[Quirin Pamp]

Hi,

I am the primary maintainer of the pulp_deb plugin (https://github.com/pulp/pulp_deb/) of the pulp project (https://pulpproject.org/).
The plugin uses python-debian as its primary dependency.

Since Ubuntu has started using zstd compression for their deb packages starting with Ubuntu impish, we have not been able to upload such packages to our software: https://github.com/pulp/pulp_deb/issues/459

I have now successfully tested the following MR from your source repo, which appears to fix the problem (so long as the zstd program is independently available): https://salsa.debian.org/python-debian-team/python-debian/-/merge_requests/79
I also tried registering an account on your GitLab instance, so I might comment directly on the MR, which is pending administrator approval.

My question is if there are any plans to release a version of python-debian that includes the above MR?
I was also wondering if there is any way I can get more directly involved with python-debian development/maintenance, since this will likely not be the last time we have some need regarding this library?

Thanks for all the good work,
Quirin Pamp
