Support NLP Services for Deprel Labels

[mr-martian]

Currently, when I try to run a service for deprel labels, I get

620754 ERROR midas-loop.server.nlp.setup - #error {
 :cause Invalid probas key:
 :data {:key :deprel/probas}

I tried adding :deprel/probas to the list at

midas-loop/src/midas_loop/server/nlp/common.clj

Lines 114 to 117 in 0365e80

	(defn write-probas [node key token-probas-pairs]
	(when-not (#{:sentence/probas :xpos/probas :upos/probas :head/probas} key)
	(throw (ex-info "Invalid probas key:" {:key key})))
	(-write-probas node key token-probas-pairs))

But after recompiling, I found that the resulting .jar file would say it was running, but my browser wouldn't connect, but I expect that's an issue with my compilation environment rather than due to the change.

I missed the step of copying generated files from midas-loop-ui, after doing that, this change does what I would expect (see #6).

Correct, as documented, service outputs for DEPREL are currently not supported. Thanks for the PR--will add comments there
