- Switched from yapf to black - Reconfigure isort for black - Resolve black/pylint idiosyncrasies Note: I used `--experimental-string-processing` because black was producing "implicit string concatenation", similar to what described here: https://github.com/psf/black/issues/1837. While currently this feature is experimental, it will be enabled by default: https://github.com/psf/black/issues/2188. After running black with the new string processing so that the generated code merges these `"hello" " world"` strings concatenations, then I removed `--experimental-string-processing` for stability, and regenerated the code again. To the reviewer: don't even try to open "Files Changed" tab 😄 It's better to review commit-by-commit, and ignore `run black and isort`.
