Process NAFO landings

[andybeet]

NAFO data pull and filtering is complete. Now a review of the processing of the data to match the format of the cfdbs data pull is required.

• Tonnage class, Division codes, species codes, gear codes
• skates & hakes

[slucey]

Have made the process_foreign_data function more generic to match get_comland_raw_data. Still need to review skates and hakes.

[slucey]

Foreign data now matches domestic data. disaggregateSkatesHakes can handle both foreign and domestic data.
