//! Improvement ideas:
//!
//! X and Y coordinates are independant, so we can compute them separately, and keep track of which
//! values of X and Y can ever reach the target area, and if so, keep the step numbers where they
//! match. Some cross referencing can then isolate the valid trajectories.
//!
//! This already runs in 1ms though so... maybe later
