More Pfaff formats

After the last feature update I focused on file formats in the last weeks. Now all StitchBuddy components read Pfaff’s KSM, PCS, PCQ and PCD files, and PCS embroideries can also be written. While KSM is once again an industrial format without color information, PCQ and PCD are used for small hoopless embroideries, e. g. at a hemline. I’ve learned that there are different PCD formats, text-based and binary ones, and StitchBuddy can read the binary type, only.
