[JIM] just:in engine v.5.5

The Just In Engine application has access to the specific Video Hardware Devices (AJA/Blackmagic Design) and/or NDI® streams, it is responsible for the encoding processes and for writing the video and metadata files to the chosen destinations. Once started, it runs in the background, as all settings can be configured and applied within the Just Control application. The Just In Engine application can run on the same machine as Just Control or on a separate macOS-based machine.
