Create InvoiceStatuses and InvoiceBillingReasons classes

[adrianofo]

Hello,

I am implementing a solution that we are needing to get the Status and BillingReason properties of an Invoice.
It would be more elegant to use constants instead of strings.
Currently, they support only string values.
If possible, could you please create two static classes with constant values (for example):

• InvoiceStatuses;
• InvoiceBillingReasons;

Similar to the SubscriptionStatuses class.

These two classes will be used in the Invoice class.

Thanks,

Adriano

@adrianofo At the moment, we don't want to add enum classes in the library and we recommend that you rely on the strings directly. There's another issue discussing adding Enums in the future potentially but it's not something we're ready to build in the short term. You can follow along in #1673.

I'm going to close this out, I hope it's okay!

Thank you!
I understand. No worries.
