#AOC: Day 9 was fun again. Part 2 was surprisingly easy in Rust 😂

Mean time (including parsing):
Part 1: ~50µs
Part 2: ~50µs

All you had to add for part 2 is `.rev()` to your iterator over the input sequences.

Iterators are very powerful 🚀

- No dependencies 📦️
- <65 lines of code 🤏

You could use even less code if you just use the `parse` function on a string. But I wanted to optimize it 😛
