model trainer: speed up by waiting 15 seconds between monitor renders

Dependencies

• [2] 7ML3OFE7 Model trainer: initial train and visualize thread pair (total crust mass; todo: altitude instead)
• [3] ROQCAPZJ Begin function for showing the map (for now just opens SDL window)
• [4] IGYI5RVV Figure out how to draw on the sdl2 window
• [*] 5AMZXFS5 model trainer: function to generate inputs to pass neural network for rendering equirectangular projection
