Title: Wai-extra: reforming the Parse API

Hi there, I've made slight but breaking changes to the API of the Parser module in Wai-extra.

The two changes are:

* Rename the 'Sink' type to 'BackEnd' to avoid confusion with the 'Sink' type from the conduits package
* Use existentials to remove the book-keeping type parameter from the 'BackEnd' (previously 'Sink') type
