Add MVTAnnotationsPlugin

[gkjohnson]

Fix #1600

• Add "setResolution" to TilesRenderer
• Fix "disposeTile" events firing for internal tileset json tiles

TODO

• Add font manager, renderer
• TODO: "setRegionVisible" seems to take a "normalized range" - should be changed to be consistent?
• Phase 1: settled lines, points
• Phase 2: occupation hide / show
• Phase 3: display text
• Adjust jitter
• Clean up
  • simplify passed contents to the occupancy grid manager
• Figure out a good way to time slice addition to the occupancy grid, raycasting
  • adjust every point on terrain adjustment? Just those visible?
• Interactivity

Plans

• Fix world rotation causing all points to disappear
• Sort point annotations by embedded priority for occupation grid handling
• Improved annotation replacement-by-id logic
  • What do we do if there are no ids?
  • Confirm Ids are consistent
• Improved raycasting logic - specifically want to queue up all annotation to be "resettled" when any tiles hide / show, prioritizing them by currently visible first, then by prioritity. This will let annotations be settled correctly without too much overhead. Ideally we can limit the amount of time spend settling annotations here, as well, rather than simply running a fixed amount per frame.
• Add glyphs for visualization per annotation.
