We build the image such that you can simply use the Ubuntu package
manager to install Lua libraries. E.g., for lfs, try this:

```
RUN apt-get -q --no-allow-insecure-repositories update \
  && DEBIAN_FRONTEND=noninteractive \
     apt-get install --assume-yes lua-filesystem
  && rm -rf /var/lib/apt/lists/*
```

The pandoc versions in our images are built against the system's Lua
library, so any system-wide Lua package can be used with pandoc.

We could think about making more functions from
[hslua-module-system](https://github.com/hslua/hslua/hslua-module-system)
available in the `pandoc.system` module. See also the discussion in
https://github.com/jgm/pandoc/pull/5468
