This is an early prototype of wrapping blissdata's redis_hdf5 in silx commonh5.
It currently require a patched version of blissdata to "inject" the blissdata to hdf5 mapping.

This is similar to zarr #4350 and tiled #4121 wrappers.

I think it would be good to drop "bliss". bliss is not blissdata.

• Only kept blissdata://
• Needing https://gitlab.esrf.fr/bliss/blissdata/-/merge_requests/133
• Issue to investigate with access to group containing a stack of image dataset
• More testing

For me this is not ready for usage yet, so I'm 👍 to not delay the coming release and keep this for the next one.

Tested with latest blissdata: attributes issue fixed.

Still need to investigate issue with access to group containing a stack of image dataset
