InkHUD: add offline map tile backgrounds and zoom controls (#10785)

* InkHUD: map tile background, zoom controls, and GPS live tracking

- Map background tiles are now rendered on the display when available, compressed with LZ4 to keep flash usage low
- If no map tiles are loaded, the map applets behave exactly as before
- Zoom in, zoom out, and reset zoom (back to auto-fit) are accessible from the menu, and only appear when the menu is opened from a map screen
- The map updates automatically whenever GPS gets a new position or your phone shares a location
- The Positions and Favorites map applets now also refresh when mesh position packets arrive for your own node
- The Favorites map now shows your position on the map even if you have no favorites yet

* README Update

* Update MapApplet.cpp

* Zoom fixed

* Zoom with no tiles fix

* CI fix
