Add two new format fields for use with to_char(), to_date() and
to_timestamp():
- ID for day-of-week
- IDDD for day-of-year
This makes it possible to convert ISO week dates to and from text
fully represented in either week ('IYYY-IW-ID') or day-of-year
('IYYY-IDDD') format.
I have also added an 'isoyear' field for use with extract / date_part.
