Add other payment gateway

Hi @vox-terman,

Thank you for using Paid Memberships Pro.

You may add a feature request over here for your desired payment gateways – https://github.com/strangerstudios/paid-memberships-pro/issues

If you need this urgently here is documentation to setting up a new payment gateway – https://www.paidmembershipspro.com/gateway/adding-a-new-gateway/

I hope this helps.
