3923	Refactor allmydata.immutable.encode.Encoder to separate out the uri_extension code	itamarst		"Creating a URI extension, calculating its size, etc. are all fairly independent actions that code be in a separate class from `Encoder`. This would make testing easier, and also make it much easier to document and enforce invariants, vs. the current ""dictionary-o-things smushed into another class"" approach."	enhancement	new	normal	undecided	unknown	n/a
