Happy I decided to not actually expand anything. Manhattan distance and counting the number of empty rows and columns was plenty. Also made part 2 an added oneliner :) It's still pretty inefficient iterating over the grid multiple times to gather the galaxies and empty rows, runtime is about 17ms
I could also extract and re-use my 2D Coord and Grid classes from day 10, and learned more about Nim in the process ^^
