Invalid request content type

The 1.6.4 version is returning "invalid request content type, expecting "multipart/form-data" or "application/json; charset=utf-8" when submitting a request in the provided Sample app as well as my own created base app.

After a response from Customer Support I now know that the 'Automatic Speech Recognition' (ASR) or VoiceRequest functionality as it is called in API has been deprecated.

Here is the reference blog post: https://api.ai/support/change-log#april_26_2017

In light of this I think its best to remove the functionality from the SDK. On the iOS Xamarin library sample there is only the ASR VoiceRequest method. Even a note in the README that states the ASR functionality has been changed would be extremely helpful. Time permitting will submit a pull request with the changes.
