Add setuptools as a requirement (via pkg_resources)

[murilo-cunha]

Thanks a lot for this project! I've had it on my radar for a while but didn't have a use case for it. let me know if I need to make any changes.

Description

• Include setuptools as a base requirment

Usually, this comes with pip, but it's possible to have a virtual environment without pip installed. In my case, I'm using pdm, which does not include pip in it's virtual environments.

At setuptools==41.0.0, we get AttributeError: module 'collections' has no attribute 'MutableMapping', as it expects colllections.abc.MutableMapping.

You can reproduce it by creating a new project with pdm and adding anomalib.

This is actually a dependency for pytorch-lightening. But since it's restricted to >=1.7.0,<1.10.0 I figured we need to add the fix here.
