Template parsing does not work #73
Description
Current bug behaviour
The TiledObject.parse() function tries to find a <template> child of <object>. However according to the TMX Documentation and the dartdoc comment above the class such an element is not allowed as a child.
Expected behaviour
Tiled uses the template reference in the template attribute of <object> to find the external template file. Maybe a lookup mechanism like TsxProviders is needed.
More information
Together with the extension to TsxProviders in #70 it might be worth generalizing a Provider for Tsx, template files and images.
I would be interested in working on a PR for this, however I do not need this functionality atm, so I wouldn't get to it for a few weeks.
