Adding new Kastle 32-bit format from @xilni

As approved by @0xFFFF on RfidResearchGroup/proxmark3 and provided by @xilni, this commit adds the format into the official repo as well. As I don't have any of the cards available for testing, I have been unable to personally verify the format encodes/decodes as intended.
