Support ChargeTotalAmount in InvoiceMapper::mapLegalMonetaryTotal()

[mustafa2011]

Hi,

LegalMonetaryTotal already supports ChargeTotalAmount through:

• setChargeTotalAmount()
• ChargeTotalAmount XML serialization

However, InvoiceMapper::mapLegalMonetaryTotal() does not map this field from the input array.

Suggested change:

->setAllowanceTotalAmount($data['allowanceTotalAmount'] ?? 0)
->setChargeTotalAmount($data['chargeTotalAmount'] ?? 0);
