Add support for setting framerate, vsync pause, and reading scanline data.

Browse Source 
- FrameRate option sets device framerates from 39-111Hz
- VSyncLines option adjusts device vsync pause using st7789 "porch control" feature
- Added Rx(cmd, bytes[]) to support retrieving scanline timing data over SPI
- Added Sync functions to support syncronization of animation to vertical scanline timing
- Minor adjustments to Configure to clear screen memory before display is visible
