Merge #14802: rpc: faster getblockstats using BlockUndo data
d20d756752 rpc: faster getblockstats using BlockUndo data (Felix Weis)
Pull request description:
Using undo data for a block (rev?????.dat) we can retrieve value information about prevouts and calculate the final transaction fee (rate). This approach is about 80x faster, drops the requirement for `-txindex`, and works for all non-pruned blocks.
```
