 To handle now such read requests for our media resources we override and implement the <code>readEntityMedia(uriInfo:GetMediaResourceUriInfo, contentType:String):ODataResponse</code> method.
 For our scenario we simply have to validate the correct requested target <code>EntitySet</code>, get the key for requesting the data from our <code>DataStore</code> (which contains the binary data of our media resource), use the <code>EntityProvider</code> to write the data and at last build the <code>ODataResponse</code>.
