Add meson.build file

This simply calls 'pip install . --break-system-packages' as a convenience
wrapper so it can be included as a subproject in others that use the meson
build system. To install, simply run 'meson setup build'. Build and install
commands will not have any targets, but they will succeed nonetheless.
