Parameters
[in]vvalue to add to the JSON value we build during parsing
[in]skip_callbackwhether we should skip calling the callback function; this is required after start_array() and start_object() SAX events, because otherwise we would call the callback function with an empty array or object, respectively.
Invariant
If the ref stack is empty, then the passed value will be the new root.
If the ref stack contains a value, then it is an array or an object to which we can add elements
Returns
pair of boolean (whether value should be kept) and pointer (to the passed value in the ref_stack hierarchy; nullptr if not kept)
