standardize the forward_from_embedding method in base model

• One major issue is that the processors define the explicit input formats of our inputs i.e (time, value) or just value. Model does not.
• If the BaseInterpreter does not account for these, it does not generalize regardless. We can just make a note of what is compatible in the documentation. We can just add assert errors for the interpreter.
• Dense methods are also different than sparse categorical variables, different than temporal (time,value) problems.
• Certain models require specific adaptations of BaseInterpreter to work (i.e CNN)
