native: optimize gas per vote calculation
GAS per vote records are being returned from Seek in ascending way, and we need the last record before the specified index which is close to the current chain's height (most of the time). To optimize we can iterate backwards strting from the last record using SeekBackwards. name old time/op new time/op delta NEO_GetGASPerVote/MemPS_10RewardRecords_1RewardDistance-8 27.7µs ± 8% 30.3µs ±
