Improve ArUco markers detection
===============================
As explain in [OpenCV ArUco documentation](https://docs.opencv.org/4.x/d1/dcd/structcv_1_1aruco_1_1DetectorParameters.html), ArUco markers detection is highly configurable.
## Load ArUcoDetector parameters
[ArUcoCamera.detector.parameters](../../../argaze.md/#argaze.ArUcoMarkers.ArUcoDetector.Parameters) can be loaded thanks to a dedicated JSON entry.
Here is an extract from the JSON [ArUcoCamera](../../../argaze.md/#argaze.ArUcoMarkers.ArUcoCamera) configuration file with ArUco detector parameters:
```json
{
"name": "My FullHD camera",
"size": [1920, 1080],
"aruco_detector": {
"dictionary": "DICT_APRILTAG_16h5",
"parameters": {
"adaptiveThreshConstant": 10,
"useAruco3Detection": 1
}
},
...
```
## Print ArUcoDetector parameters
```python
# Assuming ArUcoCamera is loaded
...
# Print all ArUcoDetector parameters
print(aruco_camera.aruco_detector.parameters)
# Print only modified ArUcoDetector parameters
print(f'{aruco_camera.aruco_detector.parameters:modified}')
```
