 * @brief HAL driver for ps2 keyboards
 *
 * While ps2 keyboards are rarely seen ever in the real world, the interface still
 * exists and the bootloader, rather than using the ps2 port directly, connects it directly to your system keyboard
 * This gives us an easy way to interact with the keyboard without implementingUSB drivers.
 *
 * @see https://wiki.osdev.org/PS/2_Keyboard
