MDR (Merchant Discount Rate) for Payment Type

This is for adding merchant discount rate (MDR) for electronic payment, in Indonesia they have electronic payment like LinkAja, OVO, GoPay etc and those payments has different MDR...

for example GoPay have 1.9% MDR so if the final payment is 2000 then after the MDR it become 1962

so I hope in the future updates you included this when adding/edit payments type...

Thank You
