[Question] How to handle icons that use x infront of the set code?
Hi,

I'm experiencing an issue with some of sets that use `x` infront of the set code. The set code for Renaissance is `ren` in MTGJSON, but in order to display the icon correctly, I need to use the class `ss-xren` instead.

Is there a recommended way to resolve this discrepancy, or would it be possible to update the library to support the `ren` set code directly for the Renaissance icon?

Thanks in advance for your help!
