update type-hinting for parameters
There are a lot of places where the typing is not proper, ie param: int = None instead of param: Optional[int] = None. This difference causes type checkers to complain user side when providing None directly or not providing any param to recieve the default None. I only fixed for user facing functions to be minimal.

@Distortedlogic I don't know if you saw, given the noise in the status (sorry!). But test_numpy_sensor fails: https://app.circleci.com/pipelines/github/RedisAI/redisai-py/1087/workflows/cad0331e-f5b4-4ac8-94ed-205c98e71fcd/jobs/1927.
I approved the code, I thought it looked good.
