Changes required to release pip wheel

[larryliu0820]

This pull request updates the packaging and build process to ensure all necessary source, header, and dependency files are included in the distribution. The changes improve compatibility with C++ extensions, add new dependencies, and refine which files are packaged and excluded.

Packaging and distribution improvements:

• Added a comprehensive MANIFEST.in to explicitly include CMake files, C++ source and header files, third-party dependencies, tests, examples, documentation, and configuration files, while excluding build artifacts and unnecessary files.
• Updated setup.py to include header files in the package via a custom BuildPy class and the package_data option, ensuring headers are available after installation.
• Set include_package_data=True and refined package_data to include all headers in the include directory.

Dependency and metadata updates:

• Added new runtime dependencies: sentencepiece, mistral-common, tokenizers, and tiktoken to the install requirements in setup.py.
• Updated package version from 0.1.0 to 1.0.1 and removed support for Python 3.8 and 3.9 in the classifiers. [1] [2]
