NCNN Neural Network Inference Framework

NCNN is a high-performance neural network inference framework optimized for mobile platforms. The `ncnn` Python library provides official Python bindings, allowing users to load and run NCNN models from Python applications. It enables efficient deep learning inference on devices with limited computational resources. The library's versioning (`1.0.YYYYMMDD`) reflects a frequent release cadence, often aligned with new features or fixes in the core C++ NCNN project.
