Use Pod::Weaver::PluginBundle::KEEDI

Almost the same as [this](https://github.com/gypark/Lingua-KO-Hangul-JamoCompatMapping/pull/1), but using your own plugin bundle, since you have `SingleEncoding` in there.

I am willing to submit patches for your [other modules](https://github.com/search?utf8=%E2%9C%93&q=[-Encoding]+extension%3Aini+user%3Akeedi+language%3AINI&type=Code&ref=searchresults) that use `Pod::Weaver::Plugin::Encoding`, unless you're strongly against it.
