…of multiple byteslices (#1921) This change adds a more efficient API in tmhash with "SumMany" whose job is to produce the SHA256 sum of multiple byteslices. It is used inside crypto/merkle.innerHash which used a naive and inefficient way of hashing multiple byteslices. Benchmark results reflect these improvements: ```shell $ benchstat before.txt after.txt name old time/op new time/op delta InnerHash-8 161µs ± 1% 160µs ± 5% ~ (p=0.143 n=10+10) name old alloc/op new alloc/op delta InnerHash-8 69.1kB ± 0% 60.1kB ± 0% -12.98% (p=0.000 n=10+9) name old allocs/op new allocs/op delta InnerHash-8 24.0 ± 0% 23.0 ± 0% -4.17% (p=0.000 n=10+10) ``` Fixes #1881 (cherry picked from commit 8acc13c)
