stable release 0.1.2

what was added and works on my setup

• Android Auto on the bike's screen — Maps, Waze, Spotify, etc
• fills the whole dash, smooth, nothing cropped, no flickering, stable 24fps
• set up once — scan the QR the dash shows, and that's the last time you'll see the scanner, from now it auto-connects
• survives an ignition cycle — stop for fuel, switch the bike off and on, it re-joins by itself
• the handlebar buttons control it — ▲▼ scroll through menus, enter selects, ▼▼ = back,
  ▲▲ = home. Every one of them can be remapped, including to "navigate to a saved address"
• voice works — ask the Assistant for directions through your helmet mic, without stopping (Cardo microphone tested)
• type a destination in the app and the route appears on the dash
• sound works as usual — music and nav voice reach your helmet the way they always did
