Add optional motion parameter filtering?

[tsalo]

What would you like to see added in this software?

It might be good to let users filter the motion parameters using either a notch filter (for MB data) or a low-pass filter (for SB data) if they way.

Do you have any interest in helping implement the feature?

Yes

I foresee using filtered motion parameters in a number of fMRIPost workflows, including fMRIPost-rapidtide and maybe fMRIPost-tedana (not to mention XCP-D). Maybe we could move the filtering function into niworkflows?
