perf: store decoded rids

[dkharms]

Description

We store in the cache decompressed (but not decoded) RIDs as []byte and on each access to RID block we decode it using binary.LittleEndian.Uint64 function. This PR changes behaviour to store already decoded RIDs in the cache.

There is no memory usage penalty since we just move integers from one representation ([]byte) to another ([]uint64) without introducing new structures etc.
