Future desired changes

Convert the following dependencies to reason:

• webpack
  • use something like https://github.com/prakhar1989/ocaml-js
  • don't need any of webpack's fancy features
• ios-sim
  • this shouldn't be too hard - just use xcodebuild & parse some things
• ios-deploy
  • this has a large native objc component, which might me more difficult to translate
  • on the other hand, we could leave it as objc & just move over any js bits
