# Overview

Previously if the coproc came up later, getProperty would return the
string literal "null", which made us print the BFW. Add tests to make
sure that we don't do that anymore by rebooting a sim coproc +
robot in a combination of different orders.

Automatically starts a TCP server in C++. Also adds warnings to Python.

This works around a change made to the default QuadThresholdParameters in the WPILib AprilTagDetector for 2025.

This is quite an odd issue/fix. 

So this is what happened... Photonvision booted with the camera
connected and the camera was working...
After a short time the camera stopped working (for some reason maybe
static, maybe temp, maybe wiring, idk).
During this time pv showed

PvCSCoreLogger] [ERROR] CS: ERROR 40: ioctl VIDIOC_QBUF failed at

I went over and played with the wire. The camera fully disconnected but
it ended up "reconnecting"
When the camera was "reconnected" photonvision detected a "new camera"
except this time with no otherpaths (aka no usb path, or by id path).
That resulted in pv creating a new camera configuration for a camera
with no otherpaths
Cscore then started to report errors that look like it attempted to
connect to the same camera twice

This fixes it by filtering out USB cameras that have no otherpath on
linux.

We've moved the install script to photon-image-modifier. This updates
the install script in photonvision to just download and run the
install.sh from photon-image-modifier.

Fixes GPL violation, the license has been missing since 2024.
This also puts licenses in as many JARs and native library archives as possible (for good measure.)
