Currently the C preprocessor is used to remove comments from the text files before encoding them. However the option used (`-fpreprocessed`) is only supported by gcc – but not by clang, which breaks the macOS build. By using Python to remove comments, we can remove the use of this gcc-specific option, and fix the macOS build.
