Integration with SpikeInterface (for spike sorting and file conversion)

Hello,

I am a developer on the [SpikeInterface](https://github.com/SpikeInterface) project which is a unified framework for spike sorting. I recently met with two developers of NIX and discussed potential synergy between our two projects.

A big part of our project is a standardized file API which allows users to quickly get their data into SpikeInterface for analysis and convert between formats. The [spikeextractors](https://github.com/SpikeInterface/spikeextractors) module is where we implement all of our file IO.

We would love to have the NIX file format supported in SpikeInterface which would allow NIX users to spike sort their data with a variety of algorithms and also convert other formats into NIX. If you could help us create a RecordingExtractor and/or a SortingExtractor for NIX, that would be a great help. We have some documentation for implementing extractors here:

Hopefully this is of interest to you as well!

Best,
