Fix type issues in options.py

[Dorukyum]

Summary

Creates a new type for allowed input types and updates option type parsing to remove all type issues.
The option type should be added to the documentation and we should make sure it's not missing any type.
Also the parsing should be tested for all cases. Done

So I decided to expand the PR just a little bit and fix every single type issue in this file (there were like 46 after InputType)
Any contribution is appreciated!
