Upgrade to RxJS 6 or add rxjs-compat dependency

[johngrogg]

When using rxjs-grpc with RxJS 6, rxjs-compat is required because of the use of the following import pattern:

import { Observable } from "rxjs/Observable";

With RxJS 6 it should be updated to:

import { Observable } from "rxjs";

See ReactiveX/rxjs#3764 for more details

Look if PR #35 solve your issue!

If you need rxjs6 support, please use rxjs-grpc@rxjs6 prerelease version.
From version 1.0-rc.0 it will be officially supported, however, there will be other breaking changes as well.

Internally to the project, with a fresh npm install (V6.3.3) the node-modules/rxjs/util folder still refers to the rxjs-compat.

Released in v0.2.0.
