Small changes.
First test version on 'Gong Zhu'.
Use a class to return card info.
Now the `test_gz` script is working properly.
Refactoring.
A beta sub-module for 'Gong Zhu'.
Beta version.
Fix: the return value of the `interpret_packet` should be a tuple, not a
formatted string.
Fix: the values of `default_deck` should be a list so that they are
mutable.
Print the card name, instead of its tuple.
Prettier output.
Still one bug remaining: `reset_deck` not work as intended.
Now the deck will be force reset.
Use @staticmethod to simplify methods a bit.
Bump to version v0.1.4: Add support for 'Gong Zhu'.
