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.ArUcoMarker.ArUcoDetector.Parameters) can be loaded thanks to a dedicated JSON entry.

Here is an extract from the JSON [ArUcoCamera](../../../argaze.md/#argaze.ArUcoMarker.ArUcoCamera) configuration file with ArUco detector parameters:

```json
{
    "argaze.ArUcoMarker.ArUcoCamera.ArUcoCamera": {
        "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}')
```
