Short movies can now be recorded (~30 seconds, depending on disk
space), with audio. New button is added, for that, depending on state
it shows "Rec" (you can record), "Stop" (you are recording) and "Busy"
(movie is being converted).
Read .dcp files stored in the same directory as the camera configuration
files and copy over the calibration curves into the DNG files after
taking a picture.
Rename MPCameraMode to a more generic MPMode and move it along
with related functions to a new object in preparation for using
it in the device object.
clang-format always manages to mix spaces into tab-based indentation.
Since we already require an exact tab-width of 8 it makes more sense to
use spaces.
