Added new instrument (flagging app) file reading capabilities. It includes two files a flag_reader.py that takes flag.json files produced by the app into a standard intermidiate representation, and a yaml file with instrument dependent description terms. Last, we modified the filereader_registry.py to find the new instrument file reader.
