Update production tests

[Lohrer]

• Updated the test sheets
• Fixed the "program expander" and "program 2nd expander" tests that 100% just didn't work.
• Removed optical input from tests
• Fans/power/temp test now asks if a main unit or expander is being tested, and only checks that unit instead of both.
• Handle SIGINT in USB test to allow exiting before the timeout.
• Prevent multiple SIGINTs from causing multiple attempts at killing processes in tests.py
• Also updated VS code python formatting and linting settings. The Python plugin spun off the formatting and linting into separate plugins.

a single suggestion. the case could be made to either implement it or keep it as-is.

love your aesthetic, it's pleasing to read.

[rtertiaer]

suggestion: it may (or may not) make more sense to from amplipi.defaults import RCAs and use that instead of this.

I'll take a look at that. I don't think that existed when Lincoln (or much less likely I) wrote this. This change is only popping up here because of auto-format actually kicking in now that I fixed the things VS Code has been yelling at us about for weeks months years.

[rtertiaer]

it definitely did not exist before a month ago even. you could definitely leave it for future refactor, np.

[Lohrer]

Apparently I broke mypy with a function attribute so hang tight while I blow everything up into a full on class...
