nrrd_write — FILEIO nrrd op

• Data kinds: any → any

• Call: import fullseye as fs; fs.ledger.nrrd_write(array, *, meta, encoding) (to call the implementation directly, import fileio; fileio.nrrd_write(array, *, meta, encoding); from the registry, opsfileio.get("nrrd_write"))

• GPU: none (CPU reference implementation only)

Usage

Write a multidimensional array and space directions as raw/gzip NRRD bytes.
