add: event-tree generate lazy-seq of xml.Event objects
ref: trying to implement my Events sequence from sax-js ones
ref: First version based on clojure.data.xml difference

Not async and not very memory friendly as we do not generate a lazy sequence of the data.xml.Event objects.
ref: Use clojure.data.xml tests
fix: DOCTYPE test contained error in input string
add: Test cljs-http library
