redux-observable-es6-compat

this is fix for package redux-observable in es2015 target build
related to: https://www.npmjs.com/package/redux-observable

issue createStore redux with redux-observable middleware in angular project target to ES6

``
Error
ActionsObservable.js:30 Uncaught TypeError: Class constructor Observable cannot be invoked without 'new'
at new ActionsObservable (ActionsObservable.js:30)
at epicMiddleware (createEpicMiddleware.js:24)
at redux.js:615
`

That error fixed in package redux-observable-es6-compat only for redux-observable version 1.0.0

instead of
`js
import { createEpicMiddleware } from 'redux-observable';
`
use this
`js
import { createEpicMiddleware } from 'redux-observable-es6-compat';
``

and it works for es5 and es2015 target build
