New mingw-python-* dependency generator + review requests

[Sandro Mani]

Hi

In mingw-filesystem-131 I've landed a new dependency generator for 
mingw-python packages, which uses pythondistdeps.py like the native 
python packages. This revealed two packages with unsatisfied 
requirements, which are therefore now FailsToInstall. I've submitted the 
two missing packages for review, which I'd appreciate if someone could 
review:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=2053753 - 
mingw-python-charset-normalizer - needed for mingw-python-requests
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=2053761 - 
mingw-pyproj - needed for mingw-python-OWSLib

Both are straight forward mingw-python packages. Happy to review in 
exchange.

Thanks
Sandro
