	Utility that performs several consistency checks on the repo. This includes:
	- checking all models are properly defined in the __init__ of models/
	- checking all models are in the main __init__
	- checking all models are properly tested
	- checking all object in the main __init__ are documented
	- checking all models are in at least one auto class
	- checking all the auto mapping are properly defined (no typos, importable)
	- checking the list of deprecated models is up to date

	Use from the root of the repo with (as used in `make repo-consistency`):

	```bash
	python utils/check_repo.py
	```

	It has no auto-fix mode.
