OpenTimelineIO Support in VSE

The Goal of this project is to add the functionality to import and export OpenTimelineIO (.otio) files in Blender. OpenTimelineIO is an open-source interchange format and C++ API that represents an editorial cut as a structured, JSON-serialized object graph carrying precise cut information, media references, markers, transitions, and effects across non-linear editors (NLEs). With the ability to import and export .otio files in Blender, the artists would be able to work using different softwares on the same timeline keeping Blender in their production pipeline.
