Code Review

This pull request does a good job of cleaning up several stale third-party dependencies, which is a good maintenance task. The changes mostly involve removing files and updating build configurations and license files. The removals of cnpy, zlib, libcrc, and mlperftiny seem correct and are consistently applied. However, I've found a couple of potentially incorrect removals from the main LICENSE file for dependencies that appear to still be in use. These could lead to license compliance issues and should be addressed.
