Drop support for Python 3.6-

[h5rdly]

Hi,

This came up when I was checking out TUI libraries to replace urwid, and encountered textual.

It is from the authors of rich, and so runs on Linux/Mac/Windows.

It supports Python 3.7+ - https://github.com/Textualize/textual/blob/main/pyproject.toml

If I were to start looking into swapping urwid, then new versions of PuDB would lose support for deprecated Python versions (Python 3.6 is no longer maintained - https://endoflife.date/python), so I was wondering if that would be agreeable.

Thanks, Eli

Dropping 3.6 is just fine; I don't see a strong justification for keeping it.

As I'm sure you're aware, changing TUI libraries is not a small task...
