How to use the oscpy.parser.read_message function in oscpy

while time() < timeout:
        n += 1
        p, s = format_message(b'/address', pattern)

    size = len(p) / 1000
    print(
        f"formated message {n} times ({n / DURATION}/s) "
        f"({n * size / DURATION:.2f}MB/s)"
    )

    n = 0
    timeout = time() + DURATION

    while time() < timeout:
        n += 1
        read_message(p)

    print(
        f"parsed message {n} times ({n / DURATION}/s) "
        f"({n * size / DURATION:.2f}MB/s)"
    )


    n = 0
    timeout = time() + DURATION

    while time() < timeout:
        n += 1
        read_message(format_message(b'/address', pattern)[0])

    print(
        f"round-trip {n} times ({n / DURATION}/s) "
