AZTEC: add manual FNC1 support:

Browse Source 
improve P/S vs P/L choice when have ECI;
  add ZINT_DEBUG_TEST dump
AUSPOST: allow variable length data input
DATAMATRIX: do `EXTRA_ESCAPE_MODE` processing up front & check have
  non-zero length afterwards;
  disallow `READER_INIT` and `EXTRA_ESCAPE_MODE`;
general: add new `z_zero_fill()` func & use;
  add new `z_extra_escape_position_fnc1()` helper;
  in `z_ct_set_seg_extra_escapes_eci` check position FNC1 whether
  or not have ECI
library: escape_char_process: note escaped backslash followed by
  caret by passes `EXTRA_ESCAPE_MODE` check
test suite: BWIPP: update to latest; support AUSPOST variants;
  process `EXTRA_ESCAPE_MODE` escaping up front
