Built a efficient and fast MRI compression program called KMRI!

KMRI is chunk-based MRI compression format for .nii files (Python + Zstd and C++). Got strong compression on synthetic MRI-like volumes, especially smooth data (up to ~900× in best case scenarios due to zero-block skipping). Check it out at https://github.com/Kiamehr5/KMRI and let me know what you think 💻
