Find a better way to pull the latest TV stations from the FCC

Basicially I can put my python script on a server somewhere and have it run daily or weekly, and have locast2plex pull from there when it's "scanning" for stations.

#92 has some a methodology built-in that works well. It checks every 12 hours if the file online is newer than the local file. It then keeps a copy if that, the extracted .DAT, and saves a copy in json format for future.
