Removed msgfmt

Drop built-in msgfmt

We have now the problem, that this is not building on Python 2. We either stop supporting it right now or you could rewrite it without pathlib. I added some github actions which check the install process. Please rebase this changes on master again.

I have no problem with not supporting Py2 any more, but that'd require version 1.6.0 IMHO. Probably not a bad idea in any case.

[sallner]

It should then be a 2.0. but it seems, that at least in GHA the installation does not work with Python 3. It seemed to work with tox locally though.

[smurfix]

Yeah, it should, but this isn't the only package that has taken sort of a middle-of-the-road approach on this – as strictly speaking it's not formalchemy that discontinued Py2 support but Python itself.

Hi, is it possible to deploy this as a bug fix? We need to be able to install this for upgrading to python 3.8 or above.
