pizzarr: Slice into 'Zarr' Arrays
An implementation of chunked, compressed, N-dimensional arrays
for R following the 'Zarr' specification. Provides array and group creation,
reading and writing with configurable chunk shapes, compression codecs, and
storage backends including in-memory, local directory, and HTTP stores.
Supports both 'Zarr' spec V2 (2024) <doi:10.5281/zenodo.11320255> and V3,
enabling interoperable access to large array data commonly used in scientific
computing and geospatial applications.
