More control over brute forcing about plutus

[Finn-Sionnach]

easy, just change the first def to something like ....
PK = 576460752303423488

def generate_private_key():
"""Generate a random 32-byte hex integer which serves as a randomly generated Bitcoin private key.
Average Time: 0.0000061659 seconds
"""
global PK
PK -= 1
k1 = PK
k2=hex(k1)[2:]
K=k2.zfill(64)
return (K).upper()

Not sure how to do it without global, but it hit me when I was poking about working on a counter. (which the same thing can be used for with a little bit of adjustment.)
