Reexport all operators in aioreactive.operators

[vodik]

Just noticed that some of the operations aren't reexported from aioreactive.operators that are exposed in other places (like Operations).

I'd like to see this fixed as I've been playing with Hy, which had threading macros making this the preferable way of building a stream. For example, the autocomplete example snippet becomes:

(import [aioreactive [operators :as op]]
        [aioreactive.core [AsyncStream])

(setv stream (AsyncStream)
      xs (->> stream
              (op.map (fn [x] (.rstrip (get x "term"))))
              (op.filter (fn [term] (> (len term) 2)))
              (op.debounce 0.5)
              (op.distinct-until-changed)
              (op.flat-map search-wikipedia))
