Read Key (Termios): A tiny crate to read keys on Linux without introducing a huge amount of dependencies.

fn read_key(fd: i32) -> u8; Takes in the FD to read. Blocks until a key has been pressed. This should be used with polling acceptably. It retuns a byte for the user to parse.

fn init(); Enters raw mode, and allows the keys to start being read.

fn close(): Enters cooked mode. Read_key() will not work after this.
