Incorporate timestamps from orcanode

[mcshicks]

The player should be able to take advantage of timestamped .ts files from orcanode. Like if someone hears something moving back to relisten so it can make a note of the time, etc.

This is partially accomplished now via the new (v3) reports list -- because it allows playback of annotated detections and candidates. For this reason, this issue could be closed for now...

...but it might be worth retaining and refining.

For example, Steve's @mcshicks suggestion could also take the form of a new data views/UIs like a table of completed bioacoustic bouts (all detections and candidates grouped together into an event with a single start and end time). This could be useful for both concerned community scientists (listeners) and professional conservation scientists (moderators) and entail development of new UIs -- like a moderator UI feature for specifying the start/end time of a bout, and a concerned community scientist UI feature for "Greatest Hits" of all Orcasound and/or a particular feed.

Any such new features, though, should likely await a major revision of the orcanode code @paulcretu , including revisiting how .ts segments are named by ffmpeg (i.e. with/out a timestamp embedded in the filename).
