zarr IO for templates object

Thanks a lot! Just because I'm also playing with the Templates, with such a PR, will be able to load/save templates as we can currently do with sorting/recordings ? Can we have a save() function that will keep the same syntax as for other objects?

@yger for now let's keep the to_zarr/from_zarr. We can refactor the calls later

@samuelgarcia ready to merge on my side. Wanna take a look?

Thanks a lot for this this will be usefull.
Amybe we could add also the possibility to give an existing zarr folder and append this temapltes to specific sub group.
We have this in zarr sorting:
https://github.com/SpikeInterface/spikeinterface/blob/main/src/spikeinterface/core/zarrextractors.py#L176
https://github.com/SpikeInterface/spikeinterface/blob/main/src/spikeinterface/core/zarrextractors.py#L324

This can be convinient to save templates + other suff.

If you do not have time this is already OK for me. No worry.

@samuelgarcia totally agree about that.

Let's do it now. In fact, when I was working in the zarr io for probe interface I came to the conclusion that that is the best pattern. In fact, we picked the same name convention and all:

I am wondering if you guys could check that one quickly in probe interface so I can save the probe to zarr completly instead of saving it as a dict as I do here:

SpikeInterface/probeinterface#250

@samuelgarcia I added the requested method.

This should be ready save using the zarr machinery developed on the probeinterface side:
