Add kwarg checker

[cthoyt]

trafficstars

This PR implements a pseudo-static type checker that takes a given dictionary to instantiate a given class and checks if it is correctly formatted. It raises an exception if it does not suffice.

This will be obviously useful for complex classes like PyKEEN models

DON'T MERGE WITHOUT 100% COVERAGE

finally, a proper opportunity to ensure this thing, because I basically just wrote a static type checker and i'm sure there's tons of stuff missing
