Issues building dependencies with Python 3.12

[gwiedeman]

Describe the bug Some dependencies that get built locally, like typed-ast and libpff-python, have trouble installing on Python 3.11. This is probably mostly an issue for Windows and slim docker images.

For slim docker images, this is resolved by installing gcc:

apt update
apt install gcc

Most Linux distros and MacOS should already have this and build okay. This is a bigger issue for Windows, as even though everything builds fine on Python 3.10, there are no official installers for old Python versions now.

To Reproduce Steps to reproduce the behavior:

1. Install Python 3.11
2. run pip install mailbag

[gwiedeman]

There are still Windows installers for Python 3.10.11 which can be used to install mailbagit. However libpff-python still often has issues building with certain versions of Windows C++ build tools.

[gwiedeman]

Update, as of January 2024 mailbagit and libpff-python in particular seems to build fine on Python 3.11, but there are issues with Python 3.12.

[gwiedeman]

The 3.11 seemed to resolve itself as dependencies were updated, so I'm going to hold off one for a bit.
