Allow for subsampling of featured trajectories

[Justin-J-Miller]

Clustering on subsampled data is useful for both memory efficiency but also time to compute kmedoids updates. Would be nice to add the option to subsample featurized datasets at the point of clustering.

Is this really not available?

It looks like cluster.py at least theoretically has an option for this:

It's supported for trajectories, but for features/h5 files it is currently disallowed:
