Tile map image

[kylecorry31]

Rather than using the subsample image view, use a custom map tile layer (does basically the same logic). This will allow for rotation as well.

• [x] Determine available tiles based on zoom level
• [x] Determine which tiles are visible
• [x] Load and display visible tiles
• [x] Adjust tiles on pan, rotate, and zoom
• [x] Tile PDF
• [x] Tile image
• [ ] Create a map layer for displaying tiles
• [ ] Replace subsample scale image view in photo maps

This will also need to handle different projections

A temporary solution could be to create a version of the ImageDecoder in the image view which operates on a tile set rather than a single image.
