+A PS/2 mouse driver for the GBA. Use it to add mouse support to your homebrew games. It's a straight port from [this library](https://github.com/kristopher/PS2-Mouse-Arduino).

+⚠️ calling `activate()` or `report(...)` could freeze the system if nothing is connected: detecting timeouts using timer interrupts is the user's responsibility.
