Describe the bug
When using a DISPLAX tag supporting TUIO on a DISPLAX screen, oscpy TUIO listener crash:

❯ oscli dump -P 3333
Exception in thread Thread-1:
Traceback (most recent call last):
  File "/home/tito/.pyenv/versions/3.9.9/lib/python3.9/threading.py", line 973, in _bootstrap_inner

To Reproduce
Code example showing the issue:

import socket

message = b'#bundle\x00\x00\x00\x01\x86\xa5l+D\x00\x00\x008/tuio2/frm\x00\x00,itis\x00\x00\x00\x00\x08\xdf\xc2d\x01\xf1`\xd6\x04\x18\x92 \x08\x12*Ultra 023009000107\x00\x00\x00\x00\x00\x10/tuio2/alv\x00\x00,\x00\x00\x00'

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.sendto(message, ("127.0.0.1", 3333))

Expected behavior
I should not expect crashing. Maybe due to type or bundle issue, will search.

Logs/output
If applicable, add screenshots to help explain your problem.

Platform (please complete the following information):

  • OS: Windows 10, Arch linux.
  • Python 3.9 + 3.11
  • oscpy 0.6.0
