OxiH5 0.1.3 — A Pure Rust HDF5 Reader, No libhdf5 in Sight

OxiH5 is the COOLJAPAN Pure-Rust HDF5 reader — it parses real HDF5 files written by h5py and libhdf5 from raw bytes, with no hdf5-sys, no C libhdf5, and no unsafe in production paths. All 11 datatype classes, every chunk index, deflate/shuffle/fletcher32/szip/nbit/scaleoffset filters, mmap, and a NetCDF-4 reader on top — part of the NoFFI sovereign Rust stack.
