Note I've removed

assert self.cursor_blob is not None

Somehow the "script" cmd is sometimes missing from the JSON response.
Only happens in some instances.

This breaks get_posts, with the error TypeError: get_page() missing 2 required positional arguments: 'selection' and 'selection_name'

I think get_photos should also extract all the other usual fields - post id, text, time etc

This would solve #111

Oops. That's embarrassing.
I swear I test my stuff in my day job

Added new "smoketest"s.

Unfortunately, photo "posts" are not real Posts.

This is all we have to work with with photo "posts":

There are no references to post_id, actor-link, page_insights or user_id.

That said, page_insights and user_id are available in the "Full Size" page.
But I feel like this can be done later in another changelist.

Fair enough, thanks for your contribution!
