Server-Sent Events support

[Banck]

Currently SSE requests (text/event-stream) don't display in Proxyman, because injectorSessionDidComplete never called, only func injectorSessionDidReceiveData(dataTask: URLSessionTask, data: Data) called

thanks @Banck Atlantis hasn't supported the SSE yet. Let me code it 👍

[NghiaTranUIT]

@Banck if you'd like to capture SSE Request, please use Proxyman because it's already supported this feature (ProxymanApp/Proxyman#1323)

For Atlantis, I will try to implement it 👍
