[MERGED PR] Adds a GPS PDA program and adds it to the default PDA programs

[Mrprogamer96]

Hey! This is my PR and I just want to clarify a few things. First, this app was not my idea, but Mrprogamer96's in the "Ideas for a Post portasci file world" thread. Next, I only gave it the basic coordinate finding function to avoid impacting balance in a major way. I'm happy to add other features if the consensus moves that way. I was hesitant to add packet functionality because if packet coordinate grabbing is on by default, one can make a mechcomp setup to grab everyone and teleport them to the crusher or do other powerful things. Again, I am happy to add packet integration if the consensus moves that way.

thank you for putting my idea into the game it self
