Refactor ZoneMap to use Mapbox

[kevinherdez]

This refactors the map views that show the polygons for the zone to use Mapbox.

• Refactor views that use ZoneMap to use MapBox #1071

Where to start

• ZoneMap.tsx and AvalancheForecastZonePolygon.tsx
  • These two files contain the bulk of the changes that relate to Mapbox. The rest of the files that were changed are mainly a result of these two

Differences between @rnmapbox and react-native-maps

• Mapbox has the idea of a Camera component that controls what the user is looking at. The Camera is used to programmatically change what the user is seeing on the map. In react-native-maps this is done directly on the MapView
• Mapbox uses layers to create the polygons that are shown on the map. They can directly receive GeoJSON data so a lot of the preprocessing that we were doing is not longer needed
• The z-index of the layers is determined by the order in which they are rendered in. The last layer has the highest z-index
  • This is why there's a conditional render for the SelectedAvalancheForecastZonePolygon component so that it's always the last one rendered
• Mapbox does not have the concept of Region that is used heavily with react-native-maps. This code will need to be refactored more. For now, the Region is being used to translate in the Mapbox equivalent of CameraBounds
• A lot of the onPresses that were passed to the MapView to handle different events are no longer required

What's next

• Refactor the WeatherStationMap.tsx
  • Refactor WeatherStationMap.tsx to use mapbox #1075
• Refactor Region calculations and remove react-native-maps
  • Remove react-native-maps #1072
• Switch to the New Architecture
  • Switch to New Architecture #1073
