ADD:  HF MFU SETUID,    this commands helps changing the UID on a magic UL, UL-C tag.
It reads block2,  since only one byte is going to change. Then it proceds to write block 0,1,2 with recalc BCC1, BCC2 bytes.

CHG:  HF MFU INFO, got some love in the form of detection of UL/UL-C/UL-EV1.  Took same idea from HF 14A READER.
