CRv2: Process postal_code attribute

[hacodeorg]

PLC-918: Use contact's postal_code to set Pardot prospect's db_Postal_Code.

• Contact's postal_code value is calculated from dashboard.users#postal_code,pegasus.form_geos#postal_code and dashboard.schools#zip.
• Prospect's db_Postal_Code is a text attribute and should show a single value.

Seeing this priority pattern for city, state, and postal code makes me wonder if it's time to extract a method for this. But when I try to imagine calling such a method, it's not much cleaner:

def self.extract_postal_code(contact_data)
  postal_code = extract_field_latest_value_with_priority(
    contact_data,
    [
      ['dashboard.schools', 'zip'],
      ['dashboard.users', 'postal_code'],
      ['pegasus.form_geos', 'postal_code']
    ]
  )
  postal_code.nil? ? {} : {postal_code: postal_code}
end

Do you think there's another way to DRY up this code, or is it better to leave it as-is?

My thought is to keep it as-is. My primary concern with this method is performance because it will be called for 4 million rows. Early return may not be the best pattern but it is slightly faster, easier to read and leaves room for custom processing (such as converting state abbreviation to full name if state info comes from dashboard.schools).

Btw, I messed up my PRs by merging them on top of each. The changes in extract_state should not be in this PR at all.
