Automatically set goroutines based on shardSize (#5346)
Update reedsolomon library to enable feature to automatically
set number of go-routines based on the input shard size,
since shard size is sort of a constant in Minio for
objects > 10MiB (default blocksize)
klauspost reported around 15-20% improvement in performance
numbers on older systems such as AVX and SSE3
