IsSensor type hints allow multidimensional channels

[ddkohler]

I think the original typing for channel_shape did not account for the possibility of multidimensional channels. This PR lets the tuple for shape be any length of ints.

Changes

• NOTE: a hack is in place to let tests pass (fails detailed in python >= 3.12 (ubuntu-latest): non-graceful shutdown #84 ). A true fix is proposed in altered asyncio syntax #86
• IsSensor channel_shape type hint is appropriate for n-dimensional data: tuple[int] -> tuple[int, ...]
• Removed type MeasureType--I don't believe the current definition was accurate (it assumed all dict items were floats), and it is cumbersome to keep type alias definitions succinct, while adopting current type hint practices, across all supported python versions (python>=3.8).
• bumped preferred python versions for black to 3.11, 3.12
• increased tests to include python versions 3.8-3.12
• refined test recipes to remove redundant testing
• pyproject.toml: changed invalid field "project.author" to "project.authors"

TODO

• changelog
• adopt PEP 585 for changes (from __future__ import annotations)

Not sure why pytest freezes from 3.12, ubuntu-latest; will look into when I get the chance.

I agree with the primary change here, I'd tend to prefer that python version stuff be changed independently if possible (just cleaner that way)

Nothing to worry about undoing, just a preference.

That said, 3.14 is out, so may be time to go through a lot of repos and update the python version systematically. (unrelated to this change though)
