Run OpenCC in docker

Open Chinese Convert 開放中文轉換 (OpenCC) is a text conversion tool. “It supports character-level and phrase-level conversion, character variant conversion and regional idioms among Mainland China, Taiwan and Hong Kong.”

It has releases for many Linux distributions and multiple programming languages. I want to run it on the command line within an isolated environment. I don’t see a docker release, so I made a Dockerfile.
