debian: updated using https://salsa.debian.org/debian/zint as

template, props Dmitry Smirnov (ticket #147, props John Crisp);
  TODO: enable building with the GS1 Syntax Engine;
  this involved auditing copyrights which prompted the next item
  re "tif.c" and will prompt the next next item "pdf417.c"
tif.c: replaced LZW compression with tree-based one due to
  "tif_lzw.h"'s original BSD-TAHOE license which has the equivalent
  of the "advertising clause", new implementation (which is much
  faster anyway) props Harald Kuhr and Bob Montgomery
pdf417.c: TODO: Replace all code adapted from "pdf417.frm" as it
  was released under GPL v2.0 or later
pdf417.h: replace unnecessary "pdf417.frm" references with ISO/IEC
  standard as 1st step re above, some expanded comments
general: Codablock-F -> Codablock F (i.e. lose hyphen)
cmake: frontend/frontend_qt: go back to only setting RPATH on macOS
  as not Debian compatible and it seems it's not a good idea on
  Linux anyway; TODO: check BSD + other Unixes
CLI/GUI: make "--verbose" option official and document
tools/gen_eci_sb_h.php/gen_eci_mb_h.php: add SPDX Unicode-3.0;
  update haible.de/bruno tarball info - "GB18030.TXT" no longer in
  "jdk-1.4.2/" so mention "libiconv-1.11/" version instead (same)
general: add various SPDXs and normalize some Copyrights
reedsol.c: malloced `logt`/`alog` tables int -> short (slight
  performance improvement)
aztec.c: add copyrights, some code fiddling
BWIPP: update to latest
