Implement fetch and save of filtered event logs and required blocks (#445)

* Fix async block size caching for missing blocks in historical processing

* Start historical block processing only if filter logs is set to true

* Fetch filtered logs by topics and save required blocks

* Fix realtime processing start block after historical processing

* Avoid publishing events and blocks in historical processing

* Add new method to graph-node test indexer

* Get full block data for subgraph block handler only if configured

* Add useBlockRanges flag for switching between historical and realtime processing
