Update project metadata and add test data

- Changed the repository URL in the AIFotoONLUS.Core project file to point to the new Forgejo instance.
- Removed the inclusion of the XML documentation file in the NuGet package.
- Added a new CSV file containing test data for image processing, including filenames and associated text values.

+# AIFotoONLUS Number Recognition Library
+
+This library provides a small, focused engine to detect and recognize numeric
+text (digits) in images using Darknet (YOLO) models via OpenCvSharp's DNN API.
+It is suitable for batch processing folders of images or individual files.
+
+Features
+- Detection network (Darknet/Yolo) to find candidate text regions.
+- Recognition network (Darknet/Yolo) to identify digits inside detected crops.
+- Single-file and directory-level processing APIs.
+- Parallel processing with per-thread network instances for throughput.
+- Diagnostic helpers to dump network output shapes and optionally save crop images.
+
+Basic usage
+1. Create a `ModelConfiguration` instance that points to your Darknet `.cfg`
+and `.weights` files for both detection and recognition networks, configure
+confidence and NMS thresholds and provide a list of number class labels.
+
+2. Create an instance of `NumberRecognitionEngine`:
+
+```csharp
+using var engine = new NumberRecognitionEngine(modelConfig, logger: null);
+```
+
+3. Process a single image:
+
+```csharp
+var result = engine.ProcessImage("/path/to/image.jpg");
+Console.WriteLine(result.Text);
+```
+
+4. Process a directory (parallelized):
+
+```csharp
+var results = await engine.ProcessDirectoryAsync("/path/to/images", recursive: false);
+foreach (var r in results) Console.WriteLine($"{r.FileName}: {r.Text}");
+```
+
+Configuration notes
+- `ModelConfiguration` controls model file paths, input sizes, thresholds and
+  whether to save cropped images for diagnostics. Make sure the paths are
+  accessible to the process and the model files match the expected network
+  architectures.
+
+- The engine expects detection network outputs in the YOLO-style layout:
+  `[cx, cy, w, h, objectness, class1, class2, ...]`.
+
+Threading & diagnostics
+- For directory/batch processing the engine creates per-thread Net instances
+  so OpenCV forward calls can run concurrently. It also contains fallback
+  logic that will perform processing with shared nets under a lock if needed.
+
+- When `EnableCropSaving` is enabled in configuration, each recognized crop is
+  saved to `logs/crops` with a timestamp and optional context label to aid
+  debugging false positives/negatives.
+
+Troubleshooting
+- If the engine returns no detections, verify the model files are correct and
+  compatible with the expected output layout. Use
+  `ProcessFileWithDiagnostics` to inspect output layer shapes.
+
+License & Notes
+This project is provided as-is. See repository for licensing information and
+for the model files distribution terms (models are usually not redistributed
+with code and must be obtained separately).
