l1(optimization): Properly implement cursor/search for multiple values for the get_block_receipts method for redb.

[fkrause98]

Issue:

Libmdbx provides cursors for queries that involve a range and/or multiple values that are related (say, sorted keys to be collected).

I'm not quite sure yet what redb's equivalent is, but we should look into implementing this particular query with the
equivalent of cursors for this new db.
