Add debian packager

[ngaullier]

Build a .deb
To get a proper package version, this proposal is to derive the version on a git tag of the form v.
So, for example, to begin with:

git tag v1.0
Then:
make deb

Since I don't use Debian I'm not sure how useful this is. Who would create the .deb?

[ngaullier]

This is indeed a good point!
Well, if you like to, you can just add the tags in the repo, and I can create the deb for you to upload in github Releases. You can also use docker for that, I used to (usually much quicker and easier to maintain than an full vm). Not talking about github actions to automate, much overkill.
But at the end, I can understand that as of an non-user for it yourself, you probably don't feel very interested! So close the issue and I won't mind!

Since I'm not actively working on this project right now and don't use Debian, I'm going to close this – but thank you very much for the contribution!
