T55xx downlink Modes
Changes : - Added t55xx downlink protocols (long leading reference, leading 0 and 1 of 4) - Added function to all read to call differnet downlink functions (to match write) - Update functions to support using differnet downlink modes. - Added support for calling downlink modes for lf t55 read, write and detect - Added new function lf t55 bruteforcedl to support downlink modes as well as try each mode for each password in password file. for functions with downlink mode extenstion. e <mode> - OPTIONAL downlink encoding '0' fixed-bit-length (default), '1' Long Zero Reference, '2' Leading Zero, '3' 1 of 4
