*Features*

- First version: merges datasets from your actor runs in the order you list them and removes duplicates by one or more fields, matched exactly, ignoring spaces and letter case, as URLs without tracking parameters, or by similar text with a threshold you set. Keeps the first or the last copy, filters rows by simple conditions, picks, removes, renames and flattens fields, and writes a `SUMMARY` record with rows read, filtered out, removed and written for each dataset. Reads and writes in pages, stops cleanly before the run timeout or the memory limit, continues after a migration to another server, and works as an integration of another actor.
