[DEV] Another Vault Treasure Room

Hey folks!

I'm still working away at v4.0, and don't have a whole lot of new things to show off just yet after the recent blog post, but here's one new room from a bit ago that I never showed off publicly.

This is another lower tier treasure room that just requires a bit of timing to overcome. The sentry scans in a consistent pattern, but you'll need to make use of that pillar and good timing to avoid getting caught in a scan on the way to the treasure.
