Description

In rust-multihash the digests are generic over their size. It should be possible to support arbitrarily sized Blake3 hashes. Currently the code will panic if you try a size differently from 256 bits.

Research direction

Start by locating the Blake3 implementation and the size-handling path that currently panics for values other than 256 bits. Determine how digest sizes are represented and where the existing behavior is tested; done means supported arbitrary sizes no longer panic and the relevant tests cover them.
