v0.0.1a0: Standing on the shoulders of giants

This is an alpha release to test Github Actions

There are several implementations of python binding or wrapper for MeCab-ko, but they are generally not well maintained.
I made it to stand on the shoulders of giants(well-maintained open-source projects like MeCab, mecab-ko and mecab-python3) with minimum modifications.
I initially named it mecab-ko-python3 because the package name referenced for development was mecab-python3,
it may seem a little arrogant, but to reduce confusion in the PyPI, the name was changed to mecab-ko.
(The repository is named pymecab-ko to distinguish it from original mecab-ko)
