Looks great! my only nit would be that I'd rewire this error check into an inlined version. Otherwise it seems like .ParseSelector has side-effects ( also do you even need to check .EncodeNode above? )

Goals
In preparation for adding pause/resume to the request side of graphsync, refactor some code into a request "executor module". Also properly implement skipping parts of the tree that are missing -- at the time we originally wrote graphsync, IPLD selectors had not abilty to "skip" on block load errors but now they have this ability.
