Add raptoreum CPU hashing algorithm

[Warchant]

BTCSQ should use hashining algorithm which is calculated on CPUs. One example is raptoreum -

https://github.com/Raptor3um/raptoreum/blob/master/src/primitives/block.cpp#L33-L46

Tasks:

• Add CPU hash to BTCSQ #662
• Create NPM package to easily use grhash in JS nodecore-js#49
• Use grhash NPM module in stratum vbk-ri-stratum-pool#5
• Add CPU hash to explorer vbk-ri-btc-explorer#11
• Add CPU hash to cpuminer vbk-ri-btc-cpuminer#5
