Big Hat Prototype for LilyGo T-OI Plus

The third prototype has become a functional cased project suitable for field testing and use. Progression from earlier prototype the basic circuitry has remained stable, however there are two additions in the Big Hat Rev 2.

• Added a port for a second sensor
• Added a port for external switch

Both of these additions are for testing of future expansions.
