CUDA Core Compute Libraries (CCCL) for Python

The `nvidia-cuda-cccl` Python package provides Pythonic interfaces to the NVIDIA CUDA Core Compute Libraries (CCCL), specifically CUB and Thrust. CCCL itself unifies essential CUDA C++ libraries (Thrust, CUB, libcudacxx) to offer building blocks for writing safe and efficient CUDA C++ code. This Python binding enables developers to leverage GPU-accelerated parallel algorithms and cooperative primitives directly from Python, easing the implementation of custom algorithms without needing to drop down to C++. The library is currently in 'experimental' status, meaning its API and feature set can evolve rapidly.
