This commit decouples knownGaps and Indexer. All knownGaps logic is in its own file. This makes testing and maintainability easier. We have also removed all efforts to check the `lastProcessedblock` - This is because we won't ever run into this issue (hyptothetically), because geth won't let it happen.
