Njit parallelization

[ramain]

Fix the "type scheduled for deprecation" numba error, which was complaining about Q being a list of lists with different sizes (e.g. 1024, 512, 256, ...). I now populate an empty numpy array with the Q values to pass into - the loop only indexes the specific needed values, so it changes nothing (edit - this is lies, the output is now different, debugging...)

Looks good.
Do we also want to make the pre-commit changes in this PR?

[chrisfandrade16]

maybe if you can just run it once so it cleans things up, with pre-commit run --files cpu_fdmt.py, then re-stage and commit changes (or if you did pre-commit install on your cloned local repo at least once, and commit a file's changes with cz, it should run automatically)

Sounds good, I'll make the pre-commit changes and push. The output looks good, but doesn't 100% match the previous method (perhaps from a dtype), I'm investigating that before merging
