Example loading ROM data into memory

cpu.rs

 pub fn load_game(&mut self, game: &str) {
    // attempt to load supplied ROM
    let mut reader = File::open(game).expect("Unable to locate ROM");
    let mut buffer = Vec::new();
    reader.read_to_end(&mut buffer).expect("Unable to read ROM data");

    // load ROM into memory (AFTER system reserved memory)
    for i in 0..buffer.len() {
        self.memory[i + self.program] = buffer[i];
    };
}
