RFC: python-imgviz: Repository out of sync with Archive

Hi Python Team,

I'm currently adopting python-imgviz, which has been orphaned (ITA:
#1124143). While preparing the package, I ran into an issue where I
would appreciate some advice:

The git repository on Salsa is at version 1.5.1, but the Debian
Tracker shows that 1.7.5+ds-2 is already in the archive.
It seems the previous maintainer uploaded without pushing the latest
commits to Salsa.

What would be the preferred way of handling this?

I intend to import the 1.7.5 .dsc from the archive to sync the
repository history before making my own changes.

Thanks for your help!
