Remove photospheres from Daily Challenge

Too many photospheres are just impossible to locate and it seems a shame that the one challenge open to everyone for free each day often has a round where you find yourself in a temple/hotel and all you can do is guess a random location in India.

I definitely think that photospheres have a place in Geoguessr overall, but not in a time-limited challenge format, as there is usually not enough information contained within them to make locating them in time realistic.

At least if you land on a road in the middle of nowhere you know that you can progress several kilometres in each direction and look for destination signs, road number markers, landscape features etc.
