Work out a New Zealand sick leave entitlement and the balance left.

Use for: 'how much sick leave do I get NZ', 'sick leave entitlement', 'when
do I get sick leave', 'can I carry over sick leave', 'sick leave balance',
'ten days sick leave'.

THREE RULES, AND TWO OF THEM ARE CAPS PEOPLE FORGET UNTIL THEY COLLIDE.

ENTITLEMENT STARTS AFTER SIX MONTHS of continuous employment, then ten days
on each anniversary. Nothing accrues day by day before that, so an employee
at five months has no statutory entitlement at all. This surprises people who
assume leave builds up from day one the way annual leave does.

CARRY-OVER IS CAPPED AT TEN DAYS. An employee who took none last year carries
ten, not everything they were owed.

THE TOTAL IS CAPPED AT TWENTY DAYS. Ten current plus ten carried is the
statutory maximum.

capped_by_carry_over_limit and capped_by_total_limit say which cap, if
either, bound the answer, because "why is my balance not what I counted" is
almost always one of those two.

Give daily_pay to value the balance. Relevant daily pay is what the employee
would have earned on the day taken, which is not necessarily salary divided
by 260, so treat the valuation as indicative.

This is the statutory minimum under the Holidays Act 2003. An employment
agreement may be more generous, and extra_contractual_days is where that
goes.

Args:
start_date: Employment start date, ISO format YYYY-MM-DD.
as_at: Date to calculate at, ISO format. Defaults to today.
days_taken: Days taken in the current entitlement year.
carry_over_days: Unused days offered from last year, before the cap.
extra_contractual_days: Days above the statutory ten in the agreement.
daily_pay: Relevant daily pay, to value the balance. Optional.

Returns:
Months employed, whether entitled yet, the entitlement, carry-over
before and after the cap, days taken, the balance and which caps bound it.
