Add new OpenEphys format #654
Description
OpenEphys have several formats.
The ex default format is already implemented in neo.rawio and is described here
The new default format is not implemented in neo. It is descirbed here
I guess that today all new data are recorded with the new format, we should implemented it.
Note that the new format should be easier to implemented because the structure is less ambiguous and most of the file are npy based.
The new format support subfolder "experiment" and subsubfolder "recording" that could be map "Block" and "Segment" directly.
