Improve B1 Display

[JohnAZoidberg]

• [ ] Reduce flicker
• [ ] Drawing API leaves the framework logo in the background (Might be issue in driver or image retention)
• [ ] Try HPM (High Power Mode) and see if we can make that work well
• [ ] Create more themes for turing app
• [ ] Sleep/Power savings
  • [ ] Implement sleep transitions of display controller
  • [x] Turn display off when in sleep (Does that save power? => Not much)
  • [ ] Do we want auto shutdown by ST7306? If yes, how do we power it back on?
• [ ] API Improvements
  • [ ] Investigate JBIG Format
  • [ ] Investigate FCI Format
  • [ ] Partial drawing

No B1 display in the works right now, we weren't happy with the prototype. Might revisit in the future.
