arm64 bitshuffle bench / test:bitshuffle:macos-arm64 (push) Successful in 8s
Not for merging. The main workflow is removed on this branch so a push runs only this one job: build the standalone bitshuffle test and benchmark with clang, check the decoded image hashes of one EIGER2 and one PILATUS4 chunk against the x86 decoder's, and time classic NEON vs the per-block- malloc fix vs the NEON port of hperf.
