ADD: lf indalademod output, The binary string is now printed with linebreaks every 16bits

ADD: lf awid code is modified,  some minor changes in outputs
ADD: lf t55xx write now prints the password on the same row,  looks better when using the new "lf t55xx wipe" command.
ADD: the ioprox T55X7_IOPROX_CONFIG_BLOCK block.
