Add events handling: trace/map + new view for aliggned/rasters + PSTHs

[alejoe91]

Events can be passed to the run_mainwindow either as a dict:

{
    "event_key": {
         "samples": [.....], # or time
    }
}

In case of multi segment, the events must be list of lists/arrays.

Alternatively, one can use a spikeinterface.BaseEvent object.

The Trace/TraceMap views allow to go to previous/next event (and select event type in case of multiple).
A new EventView shows aligned rasters or PSTHs.
Here's how it looks:

event-sigui.webm

• panel Trace/TraceMap

@alejoe91 I don't think you've commited the eventview

[alejoe91]

@chrishalcrow ready to test for real! :)

Lets move this events handling in a separate function no ?

[samuelgarcia]

I think we need to discuss the behavior we want.
If I understand correctly this is a psth segment by segment only.
Maybe we should also have a cumulate across segmetn psth no ?

Also the name eventview is to explore event I would call this veiw spikeonevent no ?

[samuelgarcia]

Cool.
TODO:

• psth and raster should gather acrros segments
• we should have an event_tools.py
• we should have lines and rates for the psth
