perf: do not match each token in aggregation

[dkharms]

Description

When getting tokens for aggregation, we scan each token and checking it against * -- so basically, useless computations and IO (we have to load+unpack token blocks). I suggest to return range [firstTID; lastTID].

Obviously, this optimization will have more impact on high-cardinality fields that span over several token blocks (like remote_addr or something).

I will collect better measurements but for cold queries (flushed userspace cache and page cache) I got following results:

# query: * | group by (remote_addr) | count

# Before (restart seq-db, flush page cache)
% hyperfine -r=1 'curl --json @search.json http://localhost:9002/complex-search'
Benchmark 1: curl --json @search.json http://localhost:9002/complex-search
  Time (abs ≡):         2.561 s               [User: 0.003 s, System: 0.010 s]
