Adding an allow-list to the list of packages from which imports are considered safe

[adrinjalali]

Right now the scanner checks if there is any imports from a package which is not a part of the standard library. However, when it comes to dumps of machine learning models, they are going to have imports from the used libraries (e.g. scikit-learn, numpy, scipy, lightgbm, etc).

It would be nice to have an option to include a list of libraries which are considered safe by the user, and not raise a warning on their imports.

We are planning to use this library at @huggingface, but such a modification is necessary to make it work for us. It would be really nice if we could include it in the upstream.

WDYT @ESultanik ?
