ActiveMerchant::Billing::AuthorizeNetGateway is not supporting to maestro card it should be master.
If I check ActiveMerchant::Billing::AuthorizeNetGateway.supports?('maestro') is returning false.
What if other gateways support 'maestro' but doesn't support 'master'? Looks like this might fix for AuthorizeNetGateway but break for others as it sounds specific to that gateway perhaps the fix should be there.
