Do not use iterators in find() and emplace() methods of hash tables.
...
Instead, these methods return a pointer to the required data as they are
stored inside the hash table. The caller uses overloaded functions to
get the key and "mapped" values from this pointer. Such an interface
avoids the need for constructing iterator-like wrapper objects, which is
especially important for compound hash tables such as the future
StringHashMap.

Separate the hash table interface for ReverseIndex.
...
It is significantly different from other uses of hash tables, and poses
the main obstacle to changing the hash table interface to the one that
can be easily supported by compound hash tables.
Make it explicitly separate, implement it only for a particular kind of
HashTable, and move this implementation to the ReverseIndex module.

A Proper lookup table that uses HashTable's API
...
This is the first step of allowing heterogeneous cells in hash tables.
performance test results are
```
1. HashMap<UInt16, UInt8, TrivialHash, HashTableFixedGrower<16>>;
2. NewLookupMap<UInt16, UInt8>
