- Remove IppBase.h, UseIpp.cpp, UseIpp.h and all IPP dependencies - Implement FFTW3-based convolution with performance optimizations: * Plan caching with shared_mutex for thread-safe reuse * Pre-computed kernel FFT stored in kernel_info.kernelFfts * Thread-local work buffers to avoid per-call allocation * Use fftw_execute_dft_r2c/c2r for parallel tile processing - Update vcpkg.json to include fftw3 dependency - Update GeoDLL.vcxproj to remove IPP references

PR Classification
Code cleanup and backend refactor to replace Intel IPP with FFTW3 for convolution operations.
PR Summary
This pull request removes all Intel IPP dependencies and migrates the convolution backend to FFTW3, improving portability and maintainability. The codebase now uses FFTW3 for all high-performance convolution and potential analysis.
