DATAMATRIX: add manual FNC1 support

Browse Source 
CODE128: error on unrecognized extra escape sequences instead of
  just passing them thru;
  fix possible shifting before manual FNC1 in 2nd position
  after single alpha (otherwise won't be recognized as AIM)
  fix not removing manual FNC1 in 1st/2nd position from content
  segs (as implied by symbology identifier)
CLI: warn if both "--dmre" and "--square" given (as "--square"
  overwrites "--dmre")
common: new routines `z_isalpha()`, `z_extra_escapes()` and
  `z_ct_set_seg_extra_escapes_eci()`
library: new helper `supports_extra_escape_mode()`;
  fix some error_number dups
BWIPP: update to latest, and allow for removal of DBAR_LTD_CC RHS
  quiet zones & extra row when have add-on in EAN/UPC composites
test suite: fix BWIPP escaping
manual/man/tcl: update for DATAMATRIX manual FNC1 support
Windows: resource scripts: make more consistent (libzint, CLI, GUI)
win32/README: update with MSVC 2026
