SymbolTableNode::parse_in reads the node's 8-byte header, checks the entries against the end of the file as before, and reads them in one bounded read. parse is a wrapper. New test: nodes with 4- and 8-byte offsets, valid and with a bad version, at two offsets and cut at every length, parse identically through a read_at-only CountingStorage.

no_stdsupport (disablestdfeature)- Optional parallel reads via Rayon
- SHA-256 provenance tracking
Usage
use clawhdf5_format::Superblock;
let data = std::fs::read("data.h5").unwrap();
let sb = Superblock::from_bytes(&data).unwrap();
