Issues with JSON files which are not queries?

[c-martinez]

Hey @pasqLisena,

I just ran into a funny issue, where grlc is trying to parse a JSON file as a query as json. Do you know if we have a good way of deciding "this is not a json file we can process as a query"?

I am guessing this might be similar to the issue I had with pre_process function in #9,and that for a JSON file to be a valid transformer query, it needs to have a proto or a @graph element. Is that correct?
