DEV: skip pandas/__init__.py in isort's pre-commit hook
I noticed that when you modified `pandas/__init__.py`, isort actually completely reordered it when using pre-commit hook. Apparantly, isort ignores the skip config when you explicitly pass a path to isort (pre-commit basically does `isort pandas/__init__.py` when that file changed).

See https://github.com/pre-commit/mirrors-isort/issues/9, which suggested to add this exclude to the pre-commit config (although that duplicates the "skip" information from setup.cfg)
Thanks for tracking this down. I wondered why the config was being ignored.
