komodo_checkPOW (fast) is called early in the process and should only refer to data immediately available. it is a filter to prevent bad blocks from going into the local DB. The more blocks we can filter out at this stage, the less junk in the local DB that will just get purged later on.
komodo_checkPOW (slow) is called right before connecting blocks so all prior blocks can be assumed to be there and all checks must pass
commission must be in coinbase.vout[1] and must be >= 10000 sats
PoS stake must be without txfee and in the last tx in the block at vout[0]
