rhg: reduce verbosity in path_encode by using a trait for writing Hopefully this makes the code easier to read and understand and shorter overall. It also lets us later tweak the type we use as a [Sink], without having to change the encoding functions, including using two different types for size measurement and for the actual serialization.
