Remove double try/except

[jeromelecoq]

Can this be simplified?

aind-ophys-motion-correction/code/registration.py

Line 822 in fdcafd1

def get_frame_rate_platform_json(input_dir: str) -> float:

There are 2 layers of try except

[jeromelecoq]

Correction 3 layers as the function is also called in a try except.
I don't think we need a separate function. This is called only once.

[jeromelecoq]

In my view, if the frame rate can't be found, we should let this module crash.

Frame rate is now grabbed from the session json. @jeromelecoq, this is in a draft PR on motion correction. Can you confirm that you are OK with this solution.
