Data Languages should provide `.Interpreter`s

[StartAutomating]

Data languages are encouraged to provide an "Interpreter" in the form of a [ScriptBlock] that easily loads that content type. For example, with .xml, this would attempt to load the first argument as XML.

Additionally, a few simple scenarios can be supported out of any arguments:

• String arguments can be interpreted as either "dot chains" or additional files
• ScriptBlock arguments can be interpreted as a Foreach
