UDP Support -- maybe don't do

[sabjorn]

with the regular Python socket, sending and receiving is a little different, from https://wiki.python.org/moin/UdpCommunication):

for UDP send

import socket

UDP_IP = "127.0.0.1"
UDP_PORT = 5005
MESSAGE = b"Hello, World!"

print("UDP target IP: %s" % UDP_IP)
print("UDP target port: %s" % UDP_PORT)
print("message: %s" % MESSAGE)

sock = socket.socket(socket.AF_INET, # Internet
        socket.SOCK_DGRAM) # UDP
sock.sendto(MESSAGE, (UDP_IP, UDP_PORT))```

UDP receive:

import socket

UDP_IP = "127.0.0.1"
UDP_PORT = 5005

sock = socket.socket(socket.AF_INET, # Internet
socket.SOCK_DGRAM) # UDP
sock.bind((UDP_IP, UDP_PORT))

while True:
data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
print("received message: %s" % data)

`recvfrom` and `sendto` need to be overwritten. But also, the size of the buffer does matter. Basically, if a user needs to send a buffer over UDP it becomes their responsibility manage how many bytes to receive and possibly reconstruct on their end... which is not ideal.

UDP might even be pointless since slicing up an `np.ndarray` into smaller chunks and sending out of order or with dropped packets will result in it being impossible to reconstruct...
