Add unit test for `FrameEditor`

The test extracts and decodes the first video frame in the test media, renders it to the frame editor's input surface and then processes data. It then reads back the output from the frame editor, converts it to a bitmap and then compares that with a 'golden' bitmap (which is just the same as the test media's first video frame).
