added check_document_exists(collection, target) -> bool (count_documents(target, limit=1) > 0) — it existed only in the talos origin and was not carried over, but the talos caller relies on it. renamed the do_upsert param to upsert on update_document/find_one_and_update/find_one_and_replace, standardizing on motor's name (the talos caller already passes upsert=). param rename is breaking; patch is fine under the no-consumer policy. bump to v0.1.1.
