Plus some tweaks to make ASCII IntCode machines slightly easier to use.
I need to figure out some good criteria for coding this robot thing to avoid gaps of all sizes. #..#.# is the first thing I'm seeing that's giving me trouble, we'd need to know 4 squares ahead of that little island that it was coming since that's how long it takes to jump and come back down. But we can't jump too soon if the gap is actually 3 wide, for example, or if the gap on the other side of the island is also going to be a problem. Ugh.
My initial idea for a solution ended up working out great, but I had a hard time getting it all down on "paper," so to speak, so this is probably 200 lines of code too many, but it definitely does exactly what I envisioned (and quickly) even if it's not the most succinct.
