text: Title: [ENH] Check number of channels and timepoints for equal length matches fit/predict for other BaseCollectionEstimator subclasses
  Body: ### Describe the feature or idea you want to propose
  
  collection estimators without the capability to handle unequal length should check the series lengths in fit and predict match
