Fix interpolations

changed milestone to %2.1.0

added BUG label

requested review from @luenensc

assigned to @palmb

@palmb you asked for my opinion on this:

As far as i can see, you are catching the case, that all the data is invalid - this means either np.nan or masked (because of being flagged higher than dfileter) - wich means that no reasonable interpolation can be done and also the subsequent methods get an empty timeseries passed - wich most likely caused the error. So doing nothing and just returning data looks consistent to me...

yes, thx 🙏
