rnz v0.3.0
v0.3.0 of rnz adds support for Zarr v3 stores following the NetCDF–Zarr (NZ-1.0) convention, alongside the existing Zarr v2 (xarray _ARRAY_DIMENSIONS) support. The inquiry and read API now dispatches against both v2 and v3 stores through the same ZarrGroup methods, with helpers in R/util.R branching on store format. New tests in tests/testthat/test_nz_v3.R and tests/testthat/test_bcsd_v2_v3.R lock in parity between the v2, v3, and NetCDF code paths. The package now depends on a remote build of pizzarr for v3 features, and the pkgdown site has been migrated to a GitHub Actions workflow.
