Type checking for lpipe provided kwargs

[Andrew-Wichmann]

If an Action doesn't have any required_kwargs and one of it's functions includes a RESERVED_WORD, lpipe will fail because the reserved word is set to None before type checking.

error message:
InvalidPayloadError Failed to run PATH1 Action(functions=[<function func at 0x7f66822c8d08>], paths=[], queues=[]) due to TypeError Type of logger should be <class 'lpipe.logging.LPLogger'> not <class 'NoneType'>.

To replicate:

def func(
    my_arg
    logger: LPLogger,
    **kwargs,
):
    pass

PATHS = {"PATH1": [func]}

To fix:

def func(
    my_arg
    logger: LPLogger,
    **kwargs,
):
    pass

PATHS = {"PATH1": [Action(functions=[func], required_params=["my_arg"])]}
