v0.1.0.0 2022-06-10
Created by unifying the vg1 and vg2 namespace dictionaries, which will be deprecated. Specifically, the new base class Voyager contains the legacy label (optional), a class describing telemetry (also optional), a class describing timing (required), and a required class describing instrument-specific parameters (currently, only ISS is implemented).
This is a preliminary non-release version. Changes have not been tracked during initial drafting, but will be henceforth.
v0.2.0.0 2022-08-23
Continuing to develop content, in advance of any use of this LDD.
Updated enumerated values for compression_state, edit_mode_id
Deleted beam, companding, elec_cal, exposure_type, filter_position, filter_step, flood, g1_voltage_count, geometry_state, image_time, image_type, pixel_dn_average_thresh, pixel_dn_average_status, shutter_exposure, shutter_reset, shutter_open, shutter_close, start_time_doy, start_time_ymd, stop_time_doy, stop_time_ymd, telemetry_mode
Deleted classes Image_Description, Image_State, and Instrument_State. The attributes that were in Image_Description and Image_State are now in the previous parent class ISS, while the attributes that were in Instrument_State have all been deleted per the line above.
Renamed data_anomaly_type to pds_source_product_data_anomaly_type
Made some attributes nillable or optional

Also moved some attributes from class ISS to class ISS_Legacy_Label, again now prepending those attribute names with "legacy_label_".
