Create alfawise_u30.def.json (#5083)

* Create alfawise_u30.def.json

I basically took the base from https://github.com/Ultimaker/Cura/blob/master/resources/definitions/alfawise_u20.def.json and compiled it with the old Cura ini given by Alfawise on the SD card.
I don't know anything about Cura config so double check it real good!
