feat(photo-viewer): add new params (#2895)

* Change for new 'headers' option

As of 1.1.19 of PhotoViewer, a new PhotoViewer option was added called 'headers' which allows for HTTP headers to be used when requesting the image.  This is useful for authenticated sites.

* Typo in example

* Added new PhotoViewerOptions

There are several other new PhotoViewerOptions besides 'headers' that need to be imported into the latest version.  I was selfishly only concerned about the one I needed, but the build really needs them all.
