lukechampine 617550f073 amortize hasher initialization for Sum256/Sum512 
As expected, the performance increase is only noticeable for
small inputs:

name            old time/op    new time/op    delta
Sum256/64-4        343ns ± 4%     243ns ± 6%  -28.96%  (p=0.008 n=5+5)
Sum256/1024-4     2.62µs ± 1%    2.50µs ± 2%   -4.57%  (p=0.008 n=5+5)
Sum256/65536-4     175µs ± 1%     170µs ± 4%     ~     (p=0.190 n=4+5)

blake3 implements the BLAKE3 cryptographic hash function.

This implementation is a port of the Rust reference implementation, refactored into more idiomatic Go style and with a handful of performance tweaks. Performance is not great, not terrible. Eventually an assembly-optimized implementation will be merged into x/crypto, and then you should switch to that. In the meantime, you can use this package for code that needs BLAKE3 compatibility and doesn't need to be blazing fast.
