[ts.parse] fix name guesstimation in guess_ts_mf

If a timestream name was given including a trailing slash, then the name
guessed (by os.path.basename) was ''. So, we use rstrip() to remove any
trailing slashes.

An additional test that ensures we remove trailing slashes from
timestream paths, so that their names are guessed correctly

Iterate thru image filenames, returing tuples of (img_path, img_cvmat)

Fix up the API of parsing thru images by time, returning None for
missing images.
