Add Int64 support (OSC Type h)

[cansik]

I have implemented the long requested Int64 support in #21 . I followed the code style of the UInt64 and Integer implementation.

Here is an example script to test it, unit tests are implemented as well.

import threading
import time

from pythonosc.dispatcher import Dispatcher
from pythonosc.osc_message_builder import OscMessageBuilder
from pythonosc.udp_client import SimpleUDPClient
from pythonosc import osc_server

HOST = "127.0.0.1"
PORT = 7500
ADDRESS = "/test"


def start_listener():
    dispatcher = Dispatcher()
    dispatcher.map(ADDRESS, print)

    server = osc_server.ThreadingOSCUDPServer(
        (HOST, PORT), dispatcher)
    print("Serving on {}".format(server.server_address))
    server.serve_forever()


def main():
    threading.Thread(target=start_listener).start()

    sender = SimpleUDPClient(HOST, PORT)
    running = True
    while running:
        builder = OscMessageBuilder(address=ADDRESS)

        # add integer with type inference
        builder.add_arg(5000)

        # add integer with explicit type
        builder.add_arg(32003, arg_type=OscMessageBuilder.ARG_TYPE_INT)

        # add integer at upper limit
        builder.add_arg(pow(2, 32))

        # add int64 with type inference
        builder.add_arg(pow(2, 40))

        # add int64 with explicit type
        builder.add_arg(34359738368, arg_type=OscMessageBuilder.ARG_TYPE_INT64)

        # epoch time with type inference
        builder.add_arg(time.time_ns() // 1_000_000)

        sender.send(builder.build())

        time.sleep(0.5)


if __name__ == "__main__":
    main()

thank you for the PR!

I'll try to find time to push a new version this weekend 👍
