CLI/lib tools to convert to/from JSON and XML

[Abscissa]

Need a library API and command line util to convert (to the extent possible) between SDL and JSON/XML.

Two ideas

• I think JSON is nowadays enough
• if it's available via cat foo.sdl | dub run sdlang > foo.json or dub run sdlang foo.sdl > foo.json that should cover most use cases?
