LL - solved small bug in plotBSTRP.m in the baseline subtraction

LL - plotBSTRP now performs bootstrapping by complete traces instead of by individual timepoints

LL - added nbstrp.m as the new standard function and included a deprecation warning in nbstrp_clean.m

LL - Updated nbstrp.m to have the same functionality of the previously tested nbstrp_clean.m
Now the function accepts non numerical group IDs and can filter out NaNs
It relies on a helper function nbstrp_get_indices.m to generate the random resampling for each bootstrap repetition. This logic can now be used for plotting as well.

LL- Updated plotBSTRP.m to return optionally the bootstrapped data and accept x_values as arguments

general cleanup on top of that

HL: testing an update for register_widefield to handle _ch525.wid single channel wf recording

threshold was too low
