Pull request description:

  ### Description

  This PR solves issue #1947 by implementing `first_seen` tracking.

  * Added `first_seen` field to `TxGraph` and `ChangeSet` so that `first_seen` timestamp can be added when inserting a new seen-at using `insert_seen_at`.

  * `first_seen` added to `TxNode` as a way to retrieve the first-seen timestamp for a transaction.

  * `first_seen` added to `ChainPosition::Unconfirmed` to order unconfirmed transactions by `first_seen`.

  * New tests have been added for the above described functionalities.

  ### Changelog notice

  * Add tracking first-seen timestamps of transactions
