Is it always a gzip file here? If so might be worth using the gzip magic bytes.

I just checked:
np.savez("test.npz", a=np.array([1,2,3]), b=np.array([1.2, 3.4]))Generated file looks just like a plain .zip file for me.
The file magic is just zip file magic "PK\x03\x04".
There is no comment in central directory to detect.
Idk if it would make sense as it might conflict with a zip files in the future.

It's okay here, don't worry. FileIO queries the file/io format in the following order:
- check the extension
.npz - check if the first few bytes match the magic bytes registered for
.npzformat. - if not, return
Format{:UNKNOWN}or error.

Ok, I added them.
Either way I'm waiting on NPZ to approve this MR before we can proceed. This is why I marked this as a draft.
It's just zip file magic.
Added support for NPZ file format.
