consider implementing release channels

It seems that expo already supports this. I think this would be very useful and could speed up our development process.

There are two points that I think we would need to work out though.

• modify our CI scripts to automatically release the app on a branch push
• verify that our production release works as expected (the development version would not work since it requires a figwheel server, which would defeat the purpose of "rapid testing")

@mehdisadeghi would you like to (eventually) tackle this?

@carocad I think it would be great if we create one release per pr and later delete it. I have to try it though.
