Implement Block DB Methods (#3221)
* include new getter for block

* create block filters from indices

* give every block index a unique bucket

* construct block indices by bucket mmap

* almost done save for the block filters

* include block filters, need a few more small touches for fetching the proper indices by bucket

* full functionality to filter by parent root

* tests pass when using the same logic as attestations

* todo

* proper todo formatting

* first minimum slot range filter

* slot range filters pass

* more filter criteria passing

* tests passing

* add todos

* all block tests pass and work

* rem fmt

* range retrieval test

* fixed test conditions

* instantiate the other buckets

* simplify bucket lookups

* deprecate non map code

* revamp to remove old index prefixes

* create indices from data

* create indices from data

* fetch block roots by slot range

* better abstractions

* simpler abstractions

* roots rename

* comment

* preston feedback

* allow blocks without parent root

// it easy to scan for keys that have a certain shard number as a prefix and return those
// corresponding attestations.
