What do you think about exposing an api closer to the semantics of a statsdclient? E.g., something like `AssertStat(type, value, sampleRate) bool` (checks that a given stat and value are in the buffer), or something that will parse the raw buffer like `NextStat() (type, value, sampleRate)` (each call returns the calls in order that they were written to the buffer, parsed out)
