KNOWN BUG: Right now, it kind of defaults to Block 0 when a getparam8 failes. (like writing "hf mfu rdbl k", ie a letter instead of number). This bug is the same all over the pm3 source-code.
CHG: refactored the "hf mfu rdbl/wrbl/crdbl/wrbl" commands.
CHG: added a cauth test to "hf mfu info" command to see if the tag is a Ultralight-C tag or not.
REM: removed old comments in bootrom.c
CHG: mifare ultralight & desfire commands inside arm has been cleaned up. Next step is to refactor it into armsrc/mifaredesfire.c
ADD: added a HF MFU INFO commmand, where you can see some tag info. Used to be in the readcard command.
FIX: minor code clean up for ultralight & desfire commands in armsrc/mifarecmd.c, armsrc/mifaredesfire.c, armsrc/mifareutil.c
CHG: Lowered the default MF_DBGLEVEL, it set to MF_DBG_ERROR.
CHG: lowered a testing value for timeout in cmdhf14a.c
FIX: sprint_hex, sprint_bin has better length detection.
FIX: ui.c has removed all c99 array declarations, with malloc
FIX: hfmfmfu.c wrong length in one array caused crashes in CmdHF14AMfURdCard
FIX: cmdlft55xx.c CmdDump has now a correct pwd string.
