class JsonFileResponse in Helper 8

A JSON PSR-7 response implementation.

Allows creating a response by passing a file URI to the constructor; by default, loads the data from the file as the body (assumes the file already contains serialized JSON), sets a status code of 200 and sets the Content-Type header to application/json.
