Rewrite provider (#352)

This is essentially a complete rewrite of `YSweetProvider`. It
incorporates the reconnect logic directly in the provider itself,
instead of using the wrapper, which should make it easier to reason
about. This paves the way to beginning to extend the protocol (as
required for #306 and #308).
