Bug#989711: Version reported as 0.0.0

[Abdelhakim Qbaich]

Package: python3-numcodecs
Version: 0.7.3+ds-1

Dear maintainer(s),

Python reports the package as being version 0.0.0, since
use_scm_version is removed, but no version is set as shown in
https://packaging.python.org/guides/single-sourcing-package-version

Instead of adding another patch to handle that, I believe the better
solution would be to drop the removal of setuptools-scm as it is in
Debian and supported by pybuild.

A merge request is available in
https://salsa.debian.org/science-team/numcodecs/-/merge_requests/1

Kind regards,

Abdelhakim
