SpatialData specifications: storage format 0.4

This branch holds the storage format of the SpatialData specification, version 0.4: how a dataset is stored (Zarr, Parquet, built on OME-NGFF). It encodes version 1.0 of the abstract data model (container format 0.2), which is on the branch data-model: each part of the storage format follows the part of the data model it encodes, included from there when the website (branch site) builds the pages.

• storage-format.md: the storage format
• storage-format-conformance.md: example stores and validation
• storage-format-versions.md: all storage format versions

Every storage format version is a tag storage-format-<version>, the text as first released. This branch holds the current version, with the editorial corrections made since; how to contribute is in .github/CONTRIBUTING.md.
