Extract neural data from NWB

[alexpiet]

Is your feature request related to a problem? Please describe.
The NWB file will contain processed, time aligned data. We would like a function that extracts that data into standard dataframes

Describe the solution you'd like

• FIP
  • tidy dataframe, each row is a measurement
  • columns: timestamps, NM type, value
• Ephys
  • probably xarray, does the ephys team already have a tool that does this?

I think this should be part of a general package, aind-nwb-utils that makes it really simple to read data from NWB files into standard formats. This will be widely used across projects.
