Task to launch OpenSFM on campaigns active panoramas

We need to document and create a task (might be devieded into multiple subtask) that :

[x] fetch all active panorama of a given campaign
[x] start OpenSFM
[x] extract all GPS corrected sensors data (convert them to lla)
[x] extract orientation data convert them to degrees/minutes
[x] save this sensors data in panorama.corrected_sensors see https://github.com/OpenPathView/OPV_DBRest/pull/52
[x] If corrected sensors data aren't found (panorama not in any reconstruction) use the original sensors as corrected sensors
[x] document how to execute it (thought docopt or readme file)
