Every array in the five zarrs now uses Blosc zstd level 5 with byte shuffle, as the Open-X-Tactile submission guide requests. Array values are unchanged from v1.0.0 (each re-encoded zarr was read back and compared array by array). Archive sizes: pick_cube_place_box 44.2 GB, unscrew_bottle_cap 5.79 GB, handover 6.23 GB, pick_and_place 4.95 GB, stack_cube 3.64 GB. SHA256SUMS.txt and the READMEs are updated.
