psmooth tests - fixing typos and adding a heap implementation of sorting

Calliope testingGround : adding functions to try and improve psmooth (does not modify any core code)

replaced preprocessing of photodiode signal (extraction of frequency) with the raw signal in the case phase of the photodiode signal might be important

replaced identification of widefield data via identification by .wii instead of .wid in case we delete .wid files

fixed bug with computing frame times if widefield data has several stacks for one expid

simplified code because added some parameters to site id

added other parameters to siteid to keep consistency

added status field even to the origin expid to keep consistency
