Arithmos/HashMaps: Long identifiers keys using typified pointers

[pavly-gerges]

This PR extends the hashmaps library further and introduces unsigned long identifiers as keys for the map elements, and map these with the internal API of the hashmaps; the following is the changelog:

• Number APIs (Bitwise - Crypto - Decimal).
• Crypto API: unsigned long idenifiers hashing byte exchange and spread algorithm.
• HashMaps API: typified pointer structure as a substitute for the generic pointers and dynamic type casting.
• Updated examples to the new API changes.
• Arithmos/hashmap: fixed the rehashing algorithm by considering other branched lists and introducing the anti-collision schemes inside the rehashing algorithms.
