Add MapBox

[kevinherdez]

THIS WILL BE DELETED AND IS ONLY FOR TESTING

If anyone is interested in trying out the new mapbox integration checkout this branch and do the following:

• run yarn install to fetch @rnmapbox
• Reach out to me so I can give you the API Key to replace the process.env.MAPBOX_API_KEY value
• run npx expo prebuild --clean so that expo rebuilds the apps and correctly installs @rnmapbox
• create and run a local dev build. EXPO GO WILL NO LONGER WORK AS @rnmapbox REQUIRES CUSTOM NATIVE CODE

For Android:

• run npx expo run:android

For iOS:

• run xed ios from the avy folder (this will open the iOS workspace in Xcode)
• click run in Xcode and put the destination as a simulator
  • you may hit an error that a switch statement isn't exhaustive on a locale file
  • Go to the file and add:

@unknown default:
   return "gregory"

• run npx expo start and then hit i

Once built Go to the More tab, scroll down until you get to "Screens" under "Developer Menu", and click on "View MapBox"
