Crate zarrs_metadata_ext

Zarr extensions metadata support for the zarrs crate.

This crate supports serialisation and deserialisation of Zarr V2 and V3 extensions metadata.

This crate includes known metadata for Zarr V3 extension points (chunk grids, chunk key encodings, codecs, and data types), including:

• Core extensions defined in the Zarr V3 specification,
• Registered extensions defined at zarr-developers/zarr-extensions, and
• numcodecs codecs and experimental extensions in zarrs that have yet to be registered.

Functions for converting Zarr V2 to equivalent Zarr V3 metadata are included.
