Lua: Use pandoc-lua-marshal 0.1.5.

-   Allow any type of callable object as argument to List
    functions `filter`, `map`, and `find_if`. These previously
    required the argument to be of type `function`, which was too
    restrictive.

-   Inline: the type of Image captions is now `Inlines` instead
    of `List`.
