[DEPENDENCY] The pre-commit/mirrors-isort mirror repository is deprecated so should use isort directly instead?

[Hedda]

Probably need to update dependencies in setup.cfg plus possibly other source for isort or in other way seperate isort dependency for all zigpy libraries as upstream repo for isort has moved?

@Adminiuga This is only to bring this to your attention as I don't know the best solution for this, I just happened to stumble on the fact that the mirror of isort package for pre-commit is deprecated and that upstream isort has also recently been moved. I think that this applies to all zigpy libraries, including zigpy, bellows, zigpy-cc, zigpy-deconz, zigpy-xbee, zigpy-zigate, and zha-device-handlers, plus zigpy-znp as well?

For reference, updated now in zigpy, zigpy-deconz, and bellows:

https://github.com/zigpy/zigpy/pull/488

https://github.com/zigpy/zigpy-deconz/pull/124

https://github.com/zigpy/bellows/pull/349

See comment in https://github.com/pre-commit/mirrors-isort where is says that the pre-commit mirror for isort repository is deprecated, and to instead use isort directly.

Mirror of isort package for pre-commit split and moved

For pre-commit: see https://github.com/pre-commit/pre-commit

For isort: see https://github.com/PyCQA/isort

Also note that isort upstream recently moved from https://github.com/timothycrosley/isort to https://github.com/PyCQA/isort

Currently, the latest release is 5.5.0 (as of September 3, 2020) and since isort 5.0.0 and later it now requires Python 3.6 or later:
