DUMP_MFU: add support for MF0UL21

[tzanou]

I am trying to read a Mifare ultralight MF0UL21 and I get this dump 101:OK WITH TEXT
045C409032464E81BB48001000000001
108F0365C1D30000000000005EA7B32A

0000020103EB041D1E08E2A300000000

and the actual content is

so i guess there is no support for the MF0UL21 ?

MF Ultralight EV1 is currently not supported for this command. It looks like for your case it would be sufficient to change this line to the last MF0UL21 page address plus 1 and adjust some buffer sizes and the output.
