A context for Codec `encode_batch` and `decode_batch`

[madsbk]

Before proposing the new encode_batch and decode_batch API (https://github.com/rapidsai/kvikio/issues/248) to numcodecs Codec, I think we should introduce a new context argument similar to Zarr's Context.

This way, we can use the meta_array option to specify the output memory type of encode_batch and decode_batch.

Agreed, this would indeed be very valuable!

Closing this issue, I don't think we need this for Zarr V3
