[Feature request] dump Gym locations only to JSON

[jtmantis]

Hi,

I'd like to quickly scan my city to find all gym location without spending much time and checking all spawnpoints, would it be bossible to do that?

Already implemented. Look at the json files produced.

@qmech7k I know about gym.json file. But what I'm asking is the possibility to scan for gyms ONLY. So it would require way less time to scan the map than doing full spawn point scanning which I don't need in this case. Unless I'm wrong?
