Shop transactions statistics#51

Maybe you can add /sg stats [player/global] [day/week/month] command, that would show top items bought and sold on that day, week or month by player or by everyone? It would be very useful to detect economy exploits, which happens a lot in servers 😄

This suggestion was migrated from old suggestions made at the Discord server.

What would be the preferred format for this? Currently, I see the only reasonable format being CSV, but something along the lines of a db file with SQLite would also work for this.

Having statistics be displayed through an MC chat seems counter-intuitive due to the limits of MC chat and as such, exporting to a file makes the most sense to me. What do people think about this?
