chg: the inital modification of t55xx commands to use Marshmellows new demod functions.

fix:  merged  readblock & readblockPWD command.
      New syntax:    "lf t55xx rd <block> <password>"   -- OPTIONAL password

fix.  merged  writeblock & writeblockPWD command.
      New syntax:    "lf t55xx wr <block> <data> <password>"   -- OPTIONAL password
