add the possibility to return all the possible solutions using the from_sample_point static methods

[danielhrisca]

The CAN databases can contain restrictions for the timings:

• minimum and maximum sampling times
• minimum and maximum SJW values
• minimum and maximum number of time quanta

With this change the user can get all the possible solutions for a given sampling value and can further filter the solutions using the known constraints.

Both me and mypy do not like the different return types of the from_sample_point method. 😄

What do you think about adding another method which generates BitTiming instances:

    @classmethod
    def iterate_from_sample_point(
        cls,
        f_clock: int,
        bitrate: int,
        sample_point: float = 69.0,
    ) -> Iterator["BitTiming"]:
        ...
        yield bt
        ...

The from_sample_point method could use the generator to create the possible_solutions list and return the "best"

@zariiii9003 thanks for the pointers, let me know if the new code is ok

Looks good, could you add some trivial test?

Looks good, thank you 👍
