Fixing Meson Packaging to Generate Launcher Executable

⚠ Note: This has been fixed upstream.

1. pip download meson

2. Extract tarball and edit setup.py, adding following item to setup(...) blob:

   entry_points={
      'console_scripts': ['meson=mesonbuild.mesonmain:main'],
   },

3. pip install <path to extracted tarball>

4. meson -v to confirm executable is correctly generated and pathing set up.
