This logic is in a separate file with no dependencies so that it can be loaded and executed as soon as possible to fulfill the purpose of the protocol detection technique. The effectiveness of this is obviously subject to how web apps bundle/consume the blockstack.js lib.

Generates an authentication request that can be sent to the Blockstack
browser for the user to approve sign in. This authentication request can
then be used for sign in by passing it to the redirectToSignInWithAuthRequest
method.
Note: This method should only be used if you want to roll your own authentication
flow. Typically you'd use redirectToSignIn which takes care of this
under the hood.
