Detailed Description

    multiScan test emulator to parse pcapng files recorded from multiScan and replay the UDP packages
    to emulate a local multiScan lidar.

    The UDP Sender sends packets via UDP over localhost, Port:2115

    Usage:

    pip install scapy
    pip install pypcapfile
    pip install python-pcapng
