Version 0.4.2

This is a quick followup to LICENSE file handing to closer match the current draft of PEP 639. It also removes the automatic optional Rich logging, which doesn't work well with Pip's subprocess piping, being cropped to a very narrow width regardless of terminal size.

Fixes:

• Add License-file metadata entry & update default by @henryiii in #329
• Drop optional Rich logging/error by @henryiii in #330

Other:

• Update PyPI links by @henryiii in #331
