Don't restrict Faker to version < 12.1

[finsterwalder]

What is the reason to restrict Faker to a version below 12.1?
Looking at the release notes of Faker, I would not expect any breaking changes.
Maybe lift the restriction completely or at least raise it to the current (major-)version?

With the latest Faker version I get this error:

/opt/hostedtoolcache/Python/3.9.15/x64/lib/python3.9/site-packages/mixer/_faker.py:33: in load
    pcls, lang_found = Factory._get_provider_class(pname, locale)
E   AttributeError: type object 'Factory' has no attribute '_get_provider_class'

Looks like the change was introduced in 12.1 which explains the restriction to <12.1

Thanks, Andreas, for trying that. So a (bigger?) change in Mixer is needed, I guess. But then still it would be good to do that and not stay with an old dependency.
Using a private method in an external library is usually a bad idea to start with.... ;-)

Makes sense to me.
I'm happy to help with testing but I'm not the right person to implement such a change.

Dependabot tried to update Faker to 16, which won't work because of this mixer restriction. Can mixer be updated to support current faker?

Faker is now up to 21.0.0. Can you update mixer to support new versions of faker?

Seems it was done intentionally here c490b1f
@mtilda Is there a reason for that?
