* docs: make english README the repository's default README
some people might be scared off by a base README being in Chinese, so using a more universally known language like English seems to be more suited for open-source projects. i believe some people just come to the project, see the README and then they're frightened to even work on/with it
this is a change curated by the #33 issue
* docs: use MIT badge directly instead of relying on the repo link
* docs: make READMEs grab the license badge directly via repo's specified license
