sha3: optimizations and cleanup (#41)
* complate reset of the SHA-3 code. Affects mostly the code in sha3.go
* fixes a bug which causes SHAKE implementation to crash
* implementation of Read()/Write() avoid unnecessary buffering as much
as possible
* NOTE: at some point I've done separated implementation for SumXXX,
functions, but after optimizing implementation of Read/Write/Sum, the
gain wasn't that big
Current speed on Initial speed on i7-8665U@1.90
