Fix how cached paired planes search for movies.

[arielleleon]

aind-ophys-motion-correction copied the raw h5 file to it's results directory for decrosstalk processing. The pipeline contains a new channel connection from the raw data to decrosstalk so that the file never needs to be copied in the first place. Also added a debug mode.

looks like a helpful debug mode was added, i see no problems

[mattjdavis]

given that
"oeid" (ophys_experiment_id) is no longer used in CO era, one could relace variables names with "plane_name". just a note we could change in the future, would rather get the PR in

@mattjdavis, I put that into an issue: #24

Looks good to me.
Input parameters in some of the functions need to be documented. (e.g., def paired_plane_cached_movie: chunk_size, non_rigid, block_size, return_rframes, etc.)
