Optimize duplicate transaction input check.
Profiling showed the duplicate transaction input check was taking around
6% of the total CheckTransactionSanity processing time. This was largely
due to using fmt.Sprintf to generate the map key.
This commit modifies the check instead to use the actual output as a map
key.
The following benchmark results show the difference:
Before: BenchmarkOldDuplicatInputCheck 100000 21787 ns/op
After: BenchmarkNewDuplicatInputCheck 2000000 937 ns/op
Closes #2
