Speeds up the undistortion step by at least 2x, using caching to avoid recomputing camera mappings.

Exports the camera ID(s) with shots.geojson.
Exports camera UV undistortion mappings (added in the 352 branch). These can be used by downstream applications to undo the image undistortion (for example, to map points from a reconstruction camera back to the original images). Description of the format is in the OpenSfM source.
