extend AnnotationSeries class to incorporate other variables

[luiztauffer]

2) Feature Request

When storing annotations in the AnnotationSeries class, besides the text the only available info to add is the time. It would be useful to be able to add user-defined info, e.g. channel number, for each annotation. Perhaps it would be a good idea to make it a DynamicTable?

Problem/Use Case

There are cases when the annotations might be specific to other variables.

@luiztauffer thanks for the suggestion. We'll need to take a closer at AnnotationSeries. In the meantime, if you need a DynamicTable to annotate time intervals an alternative may be for you to simply add your own TimeInterval table with NWBFile.create_time_intervals (or NWBFile.add_time_intervals).

@oruebel thanks for the tip! I'll look into that
