Update all requirements to latest versions

[RytoEX]

Update all requirements to latest stable versions.

Also, update the README to just point to requirements.txt instead of having to update it every time.

I ran a test run on my fork and the errors were slightly clearer (Black did not error out) or the same (mypy still fails due to no mypy cache directory).
