commit 3e25052f06835a8f2038c4d4e2a694a25f399b35
Author: Frederick Yin <fkfd@macaw.me>
Date:   Sun May 31 14:52:03 2020 +0800

    Add CLI arguments to pick custom fonts
    
    Users can now pick custom fonts via args `--textfont` and `--monofont`.
    This is a WIP patch. Todos:
    - Add more font candidates to the "default" font lists
    - Add help text for arguments
    - Perhaps a config file
