v1.3.0

This release stabilises our dependencies - you can now use released versions of VirtualiZarr, Kerchunk, and Icechunk all in the same environment!

It also fixes a number of bugs, adds minor features, changes the default reader for HDF/netCDF4 files, and includes refactors to reduce code redundancy with zarr-python v3. You can also choose which sets of dependencies you want at installation time.
