Create an interface for the cd entry hash table

The current implementation of the hashtable uses less memory than
a std::map. As most of the zip files we encountered don't use the zip64
extension, we should keep the current implementation. And the interface
adds the flexibility for us to switch to std::map for zip64 format.
