Fix freakin rockets already#21785

1) a rocket shouldn’t fit inside a gap of a single pixel

2) a rocket should not splash triangle tiles THROUGH WALLS

3) a rocket shouldn’t be so ridiculously much better than c4 in nearly every situation to the point where c4 is basically an offline raid tool, given splash, range, and easier craft costs, and the fact that rockets allow the raider to basically not even consider any base-design intelligence such as traps and turrets.

Give rockets a larger hitbox, reduce splash, and give C4 splash instead
