Example use with LDtk

[thedodd]

What problem does this solve or what need does it fill?
An example integration with LDtk would be excellent. Folks wanting to use LDtk output would be able to get things integrated a bit more quickly.

Describe the solution would you like?
A simple example showing how to load & use an LDtk map.

Describe the alternative(s) you've considered?
N/A (maybe using another crate, but this one seems to be one of the best, and has all of the building blocks needed)

Additional context
Just looking for a quick way to load and use an LDtk map.
