Proof of concept of "buffer_description_api" and xarray reference API bridge

[samuelgarcia]

Given the idea of @bendichter and this gist

Here a very very early stage of a very very proof of concept of the "buffer_description_api" for analogsignal chunk.

The idea/goal is:

• have a simple buffer description for analogsignal for binary or hdf5 cases (maybe more)
• this description can be exported to json
• this description can be easily transformed to the xarray/zarr reference external API
• make so file cloud ready for streaming chunk of traces

Merci beaucoup @zm711 and @h-mayorquin for the review

@zm711 @h-mayorquin @alejoe91 This is OK on my side. test are passing I think we can merge this soon. we will be able to update stream and buffer on reader per reader basis later.
