React Native with Expo Discovery

[kaseywright]

The purpose of this issue is to track the progress of discovery with Expo for Fluent mobile.
The tasks that should be accomplished are:

• Setup local development environment
• Scaffold a basic PoC application
  • Basic navigation - can we easily create and navigate views
  • Sqlite - can we easily do CRUD operations with local SQLite
  • Audio - can we:
    • record audio: what formats (encodings) are easily supported (ex. webm, mp3, etc.)
    • playback audio: can we easily scrub through an audio recording
    • editing audio:
      • join (splice) recordings end-to-end, split one in the middle and insert another, etc.
      • trim from the start and/or end of a recording
      • cut recordings into two or more pieces
• Record findings in a document: this one can be used as a template.

Note: PoC source code can be committed to this repo as a PoC branch or in a separate repo. Other tasks for discovery, such as app store deployments, will be covered in separate tickets.
