🎉 Invoice discounts, construction reverse charge, and per-invoice rounding control.

API improvements

• Line item discounts are now supported on invoices. Set a percentage or fixed-amount discount on an invoice line item when creating or updating an invoice; the discount is returned when fetching invoices.
• Construction reverse charge is now supported on invoices. Set reverseChargeType to construction on an invoice line item when creating or updating an invoice.
• You can now mark a customer as eligible for construction reverse charge with constructionReverseChargeEnabled when creating or updating a customer. The value is returned when fetching customers.
• You can now set totalRoundingEnabled per invoice to choose whether the invoice total is rounded to a whole number when creating or updating an invoice. When omitted, the company default is applied.
• Custom unit types are now supported on supplier invoice line items when creating or updating a supplier invoice, matching invoices.
