Need to add doc string and add datatypes to function args

Description of the change
This PR enables faster loading of a quantized model by calling only the functions/sub-functions needed to load a model while ignoring the functions needed for quantizing the model. An inference argument was added to the fms_mo argument to activate the function.

None
How to verify the PR
The PR is validated by performing Direct Quantization with Smooth Quant and parsing the inference argument with the rest of the argument. The validation was done with/without Qbmm.
