Add new parking space CDU code to nonlivable construction

[wrridgeway]

Since we don't have any 'PS' CDUs yet, this code shouldn't result in any changes to our data, and doesn't:

select
	count(*)
from iasworld.oby
where user16 = 'PS'

yields 0, as does

select
	count(*)
from iasworld.comdat
where user16 = 'PS'

select
  is_parking_space,
  parking_space_flag_reason,
  is_question_garage_unit,
  is_common_area,
  'old' as source
from default.vw_pin_condo_char

union all

select
  is_parking_space,
  parking_space_flag_reason,
  is_question_garage_unit,
  is_common_area,
  'new' as source
from z_ci_add_new_parking_space_code_to_nonlivable_construction_default.vw_pin_condo_char
