ARM-based machines populate the device model into Device Tree. We can
use this information to automatically detect and report the hardware
model for most Single Board Computers (SBCs). Vendors who want to
override this can still do so via the value in the configuration
database.
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
Jul 04 06:25:18 BackLeft java[643]: [2024-07-04 06:25:18] [CSCore -
PvCSCoreLogger] [ERROR] CS: ERROR 40: ioctl VIDIOC_QBUF failed at
UsbCameraImpl.cpp:723: Invalid argument (UsbUtil.cpp:156)
Jul 04 06:25:18 BackLeft java[643]: [2024-07-04 06:25:18] [CSCore -
PvCSCoreLogger] [WARN] CS: WARNING 30: BackLeft: could not queue buffer
0 (UsbCameraImpl.cpp:724)
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.
# 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.
Rotate camera calibration coefficients based on camera rotation. Probably. Seems to work. Maybe.

fixed the unpacking order to match the current pipelineresult data layout.
* fix positioning of multitarget struct in pipelineresult unpack
* fix encode order in PhotonPipelineResult.cpp
* [photon-lib java] Fix classes with protobuf support not "announcing it"
Since they didn't implement `ProtobufSerializable` this meant that most other software didn't even know protobufs were even implemented.
In AdvantageKit for example this would cause it to not work it all and crash.
* Run `spotlessJavaApply`
Allows logging software and live data view to see results. Also removes the requirement for AScope to keep up with the packet serde schema and instead just use the Protobuf descriptor.
Follows a similar system to the current Protobuf implementation that helps make code more readable and expandable. Also wraps the NT topic to be more useful. Impl stuff is hidden so it can't be extended. Optimizes AT-specific classes by only serializing data when needed, won't save on size but will on time.
closes#1003
* add classes to targeting and update gradle

* make comments better about x and y relationship
- Aruco pipeline now infers tag width from tag family like the AprilTag pipeline
- Removes unused Aruco and 200mm AprilTag models
- `VisionEstimation.estimateCamPosePNP()` now requires a target model instead of assuming 16h5
- Multitarget pipeline similarly infers target model of tag family now
- `PhotonPoseEstimator` can have target model set for on-rio multitarget

### What does this do?
- Deprecates previous sim classes
- Has a `CameraProperties` class for describing a camera's basic/calibration info, and performance values for simulation. Calibration values can be loaded from the `config.json` in the settings exported by photonvision.
- `OpenCVHelp` provides convenience functions for using opencv methods with wpilib/photonvision classes, mainly to project 3d points to a camera's 2d image and perform solvePnP with the above camera calibration info.
- `TargetModel`s describe the 3d shape of a target, both for projecting into the camera's 2d image and use in solvePnP.
- `PhotonCameraSim` uses camera properties to simulate how 3d targets would appear in its view, and has simulated noise, latency, and FPS. For apriltags, the best/alternate camera-to-target transform is also estimated with solvePnP.
- `VideoSimUtil` has helper functions for drawing apriltags to a simulated raw and processed MJPEG stream for each camera using the projected tag corners.
- `VisionSystemSim` stores `VisionTargetSim`s and `PhotonCameraSim`s, and is periodically updated with the robot's simulated pose. When updating, camera sims are automatically processed and published with their visible targets from their respective poses with proper latency.
### What's still not working?
- Mac Arm builds are broken
- More examples
- Update website/docs
