With older versions of prettier, when the hook failed a bunch of
"[error] No parser could be inferred for file: {PATH}" error lines
showed up because of lack of support of a flag that pre-commit
passes for us by default. It made figuring out why the prettier hook
failed annoying.
This fixes Prettier install failures similar to those seen in
https://github.com/prettier/prettier/issues/9459, and is the solution
recommended there.

Since pre-commit 2.9.0 (2020-11-21), the types_or key can be used to
match multiple disparate file types. For more upstream details, see:
https://github.com/pre-commit/pre-commit/issues/607
Add the minimum_pre_commit_version to require pre-commit 2.9.0+.
Fixes#402
To avoid hitting a mypy bug causes pre-commit to always fail on CPython
3.9. Even though it's still an outdated version, the bug effectively
blocks development on CPython 3.9 so that's why this commit exists
instead of waiting for cooperlees to finish his bump to 0.790 PR.
Also this fixes primer to ensure it always raises CalledProcessError
with an int error code. I stole the patch from cooperlees's mypy bump
PR.
It's funny how mypy 0.790 is already asked for in our
Pipfile.lock file, but oh well mypy is probably more commonly run
through pre-commit than standalone I guess.
Oh and if you're curious why the bug doesn't up on CPython 3.8 or lower:
there was some subscription AST changes in CPython 3.9.
- Move black.py to src/black/__init__.py
- Have setuptools_scm make src/_black_version.py and exclude from git
- Move blackd.py to src/blackd/__init__.py
- Move blib2to3/ to src/
- Update `setup.py`
- Update unittests to pass
- Mostly path fixing + resolving
- Update CI
- pre-commit config
- appveyor + travis
Tested on my mac with python 3.7.5 via:
```
python3 -m venv /tmp/tb3
/tmp/tb3/bin/pip install --upgrade setuptools pip coverage pre-commit
/tmp/tb2/bin/pip install ~/repos/black/
cd ~/repos/black/
/tmp/tb2/bin/coverage run tests/test_black.py
/tmp/tb3/bin/pre-commit run -a
/tmp/tb3/bin/black --help
/tmp/tb3/bin/black ~/repos/ptr/ptr.py
```
