Description

See https://github.com/NVIDIA/CUDALibrarySamples/tree/master/nvCOMP and https://github.com/rapidsai/kvikio/tree/branch-25.02/python/kvikio and https://github.com/NVIDIA/nvcomp?tab=readme-ov-file

Python bindings already exist so I think we would need rust bindings as well (although maybe we could call the python through rust with pyo3? Maybe a bad performance?). In any case, it would be great to somehow add support for this (somehow emphasized, almost certainly a lot of work) given the speed boost of not having to do the CPU bounce, and zarr-python v3 natively supprting GPU buffers if I'm not mistaken. So this should be doable, but probably a lot of work and maybe it's own package

Research direction

Start by reading the linked NVIDIA nvCOMP samples, kvikio Python bindings, and nvCOMP documentation, then review how zarr-python v3 handles GPU buffers. Determine whether Rust bindings or a separate package is needed and define done as GPU compression support without a CPU bounce; the issue does not specify files or tests.
