Use official filter canonical names as filter's `filter_name`

[t20100]

Confirmation of filter names is ongoing at the hdfgroup: HDFGroup/hdf5_plugins#255

hdf5plugin's filter_names are not fully aligned with it: "bshuf" vs "bithsuffle" (Raised in HDFGroup/hdf5_plugins#255 (comment)).

Make sure used filter_names (and eventually class name) are consistent with official canonical names, and make alias whenever possible to keep backward compatibility
