Hi

I try to find out the filename of a path in a lua filter with

    function Image(img)
        p = pandoc.path.filename(img.src)
        print(img.src, p)
        return nil
    end 

but I get an error

Error running filter dark_images.lua:
dark_images.lua:45: attempt to index a nil value (field 'path')
stack traceback:
    dark_images.lua:45: in function 'Image'

I'm using the newest pandoc 2.14.1, precompiled deb from github

For some reason, you have to load the module explicitely, so:

```
local path = require 'pandoc.path'

function Image(img)
    p = path.filename(img.src)
    print(img.src, p)
    return nil
end
```
