[Neuropixels] Support optogenetics protocol

[weiglszonja]

Support adding OptogeneticsSeries and OptogeneticStimulusSite to NWB file for optogenetics protocol.

The stimulation parameters should be updated in the optogenetics_stimulation_metadata.yaml
The behavior metadata for Bpod data with such protocols ("RWTautowait2OptoTest") is updated to include the additional state types and task arguments.
According to their protocol code (RWTautowait2OptoTest.m) the optogenetic stimulation onsets can be determined from the Bpod data:

• "IsOpto" - Whether the trial is an optogenetic trial.
• "OptoEvent" - The type of optogenetic event. (1 = center port in, 2 = side port off, 3 = Reward or opt-out, 4 = stimulation on, 5 = delay)

We construct the OptogeneticsSeries from the stimulation onsets: trials where OptoEvent = 4
And the stimulation parameters from the yaml file.

Ok, so it would use the already created trial table to buld the optogenetic series from the opto event and from metadata. Correct?

Yes the onset times are from the trials table where is-opto is true and opto event type is 4. The other parameters to build the optognetics series are from the metadata yaml file
