Store Non-Image Observation Data

[thomazach]

Each target observed by Moxa-POCS has its images placed in a time stamped directory within the images directory. In addition to raw image files (.cr2), the system should put other target information there as well. Specifically, it should put the Ra/Dec coordinates of the target, any user notes as specified by the schedule file (see /conf_files/targets/test_fields.yaml as an example), and in the future it should include weather sensor data about cloud cover. This should be done from the camera module since it already manages the directories where this new information will be stored.
