ADD:  'LF T55X7 WAKEUP' command.  For tags with AOR bit set,   send this command with password to wake tag up and be able to do a "LF SEARCH" etc on it.

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.
