Applied PwPiwi's new parity fix.
Applied Marshmellw's fixes for FSKdemod (HID, IO)
FIX: a potential bigbuffer fault given pwpiwi's change inside lfops.c CmdIOdemodFSK & CmdHIDdemodFSK
FIX: change some "int" parameters to uint's.
FIX: changed the lfops.c - DoAcquisition125k_internal to respect pwpiwi's definitions of FREE_BUFFER_OFFSET
HEADS up: The ultralight functions hasn't been verified since pwpiwi's changes.
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.
Fix: removed a call to free, which I think made linux people unhappy during "lf t55xx rd 0"...
Add: "lf t55xx fsk" now kind of outputs binary from "FSK2a R/40 R/50"..
