heading pitch and zoom map features

Hi there,

Loving some of the updates like show and hide.

I have a streetview map currently using custom code at the moment which loads the heading, pitch and zoom via a bit of .js

I have tried today to use the map function in BSS but it doesn't have the ability to specify these features.

Might be a nice feature at some point to add to the current options of the map function.

  var panorama;
  function initialize() {
    panorama = new google.maps.StreetViewPanorama(
          position: {lat: 35.7040744, lng: 139.5577317},
    pov: {heading: 96.94, pitch: 0},
    zoom: 1
