[Feature Request] HAR File support

[HelgeSverre]

HAR files is for lack of a better term a JSON dump of HTTP Requests that you can generate via the DevTools and various proxy tools, useful when there is no official api documentation and you have to reverse engineer an API by doing the good old "clicking around in the user interface to trigger all possible api endpoints manually".
