Manual labeling of detections

[xaviermouy]

The users need to be able to manually label a detection in SoundScope. The manual labels should be 1) saved in the netcdf file and. 2) exportabel in csv file along with detection results.

This will require modification of the Annotation object in the ecosound library.

Should the manual verification only have True or False capabilities (i.e. users can only indicate if the automatic detection label is correct or not), or should it have the capability to assign a different label (e.g. reassign an automatic detction to another species/call type, etc).

If the former, then we could potentially add a boolean column in the existing detections table of SoundScope. The Panel Tabulator widget (which we currently use) does allow for this (as shown in the screenshot below)
