tex-kanbun{,-doc}: Add version 1.2

This package allows users to manually input macros for elements
in a kanbun-kundoku (Han Wen Xun Du ) paragraph. More
importantly, it accepts plain text input in the "kanbun
annotation" form when used with LuaLaTeX, which allows
typesetting kanbun-kundoku paragraphs efficiently.
