Add a fast class to seek to an exact time position in a video.

This requires a higher sdk version but is completely worth it. I tried
jcodec and native ffmpeg and both have a horrible seek performance while
increasing the package size significantly. In case of ffmpeg the native
libs are around 15 Mb.
Add a ExperimentRunViewControl.

Simple view to navigate a ExperimentRunView.
Fix warning and add todo.
Make the CameraExperimentRunView working.

Put all parts together for a first working version.
