Mike Auty c64ed6a8dd Remove validity checking in favour of static-type checking.
This removes the assertions that checked plugin devs didn't do anything
overly bad in favour of using mypy to ensure appropriate type-checking.

It also moves the ProgressCallback typing information to constants in
order to avoid circular imports (since constants doesn't import
anything).
