Interested in replacing sha3 with b3sum.

[xtqqczze]

It would be a breaking change for shuf::SeededRng, but open an issue if you like.

[xtqqczze]

This comes with a forward compatibility commitment: we have to keep using SHA-3 and ChaCha12 and the current (in-tree) algorithms whenever --random-seed is passed.

1. No successful run was found on main (1ea01a3) during the generation of this report, so d41ed38 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩

2. 38 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩
