Freezes TTY when receiving any other signal besides SIGINT

Hi, first of all, thank you making this utility module!

I recently noticed while accidentally pressing any button besides Ctrl+C it stops processing further inputs, resulting into freezing TTY. A currently used workaround is wrapping the reader into a recursive function.

function recursiveListen() {
    const data: Uint8Array = new Uint8Array(1);
    Deno.stdin.read(data).then(() => {
        if (disposed) return;
        if (data[0] === 0x03) {
            onCtrlC();
        }
        recursiveListen();
    });
}
