Result aggregation for Pattern Queries

[aalexandrasilva]

Hello 👋

The original pattern query implementation included a result subsumption of the results of the instance queries.
As mentioned in version 3.3.3 documentation:

For each result (limited to 2000) a query instance will be created.

This will be done for every query in the benchmark queries. All instances of these query patterns will be subsummed as if they were one query in the results.

Currently, iguana computes the metrics separately for each of the query instances.
Would you consider adding this result aggregation back? 😄
