Feature Request: pyRACF should do Input validation

[ElijahSwiftIBM]

Is your feature request related to a problem? Please describe.
It is very possible to pass improper or non-functional arguments to pyRACF unwittingly.

Describe the solution you'd like
pyRACF should directly enforce valid types and values for defined traits based on documented RACF behavior.

Describe alternatives you've considered
The current implementation allows RACF to fail improperly defined parameters, resulting in SecurityRequestError's returned to the caller.
