Nfactor: Increases CPU & Memory Hardness

rfactor: Increases Memory Hardness
r = (1 << rfactor): How large a chunk is
pfactor: Increases CPU Hardness
p = (1 << pfactor): Number of times to mix the main chunk
A block is the basic mixing unit (salsa/chacha block = 64 bytes)
A chunk is (2 * r) blocks
~Memory used = (N + 2) * ((2 * r) * block size)
