CHG: Minor code changes on T55X7 code. Default password is back to 'FF FF FF FF',
REM: removed @marshmellow42 's wakeup option in "lf t55x7 read",
--- BASICALLY:
if a T55X7 tag has following bits set:
AOR - send wakeup command with pwd, to enable LF interacting with it.
PWD - send read/write/trace/info command with pwd. No need to send wakeup.
