Add option "all pictures"

[dennisvandehoef]

My problem starts with the fact that I am not a regular google photos user.
Though, I would like to start using them to get pictures on Home Assistant.

I have this directory "Screensaver" on my local machine, which I already fill with all images for my desktop, and they also should go to HA. So I quickly installed the sync software from Google, though after syncing I found out that there is no way to automatically add the pictures I upload to an album.

For me, the perfect solution would be to select "All photos" instead of an Album or Favorites. As the whole Idea to use this integration is to re-use a directory I already maintain on my Windows machine.

I think this is similar as the other feature request that is still open: #34.
