LIBERO-90 read-out data
The 89 LIBERO-90 task files that the out-of-distribution open-loop read-out of tr/eval_libero/lb_cluster (and
tr/eval_libero/wam_eval/lingbot) reads, byte-identical to the copies the other read-outs used. Branch lb-cluster of
mjf-su/wam-influence; the pins are tr/eval_libero/lb_cluster/inputs/readout_hdf5.json (group ood).

- Regeneration replays demos in the simulator and re-renders them; the bytes are not reproducible on another machine. Use these files, do not regenerate.
