NVIDIA cuFFT (CUDA 11 variant)

The `nvidia-cufft-cu11` package provides the native runtime libraries for NVIDIA's GPU-accelerated Fast Fourier Transform (FFT) library, specifically compiled for CUDA 11.x environments. It enables high-performance FFT computations directly on NVIDIA GPUs for various scientific and engineering applications, including deep learning, computer vision, and computational physics. This package is a low-level dependency providing the C/C++ binaries, and is typically used in conjunction with Python binding libraries like CuPy or nvmath-python. The current version is 10.9.0.58, with a relatively slow release cadence for this specific CUDA 11 variant, as newer CUDA versions often have their own packages (e.g., `nvidia-cufft-cu12`).
