zxing-cpp: update to 1.4.0.

Note: this is an intermediary release on the way to 2.0. This code
is (supposed to be) API compatible (via the ReadBarcode.h interface)
with v1.3.0 but contains quite a few additional deprecations. It
still has SO number 1, which is as wrong as it was for release
v1.3.0 and it is not ABI compatible with 1.3 either. 2.0 will be
basically 1.4 but with all deprecated API removed and the final
fix for #333.

Main changes

    Reader support for Micro QRCode by @corbers
    prepared switch from std::wstring based utf16 to std::string based utf8 \ 
results, use new ZX_USE_UTF8 macro to transition to the upcoming 2.0 API
    much improved 'binary' data support via new Result::bytes() API, see #334 \ 
for a detailed background discussion.
    new Result::contentType() API returning information about the type of \ 
content (like text vs. binary, etc.)
    better standards conformance with respect to ECI handling, see \ 
Results::bytesECI()
    support for proper ECI handling across structured append symbols (see \ 
MergeStructuredAppendResults())
    new Result::error() API with improved error handling, see also \ 
DecodeHints::returnErrors()
    removed all internal header files from the installed set, so only the \ 
ReadBarcode.h based APIs are supported from here on out
    removed all sample images from the 'source' distribution zip/tar balls (much \ 
reduced size)

Minor changes

    lots of little bug fixes
    smaller per process runtime memory (thanks to @vkrause)
    clang-13 and gcc-13 compilation fixes
    ported Qt example code to Qt6
    experimental multi-symbol detection support for DataMatrix when compiled \ 
with c++-20
    python read_barcode returns None if no symbol was found
    fix error in multi-symbol detection of linear codes (sometimes reported 1 \ 
symbol as 2)
    new -bytes and -errors options in ZXingReader
    support tryRotate for PDF417 symbols

Log message:
zxing-cpp: update to 1.3.0.

The major new features:

    Multi-barcode reading with the new std::vector<Result>
    ReadBardcodes(...) function. Does not work for Aztec, DataMatrix
    and Maxicode, yet.
    Multi-resolution scanning that can automatically downscale the
    input to substantially increase the detection rate on high
    resolution scans, see DecodeHints::tryDownscale, currently only
    enabled in the ReadBardcodes function
    New Result::symbologyIdentifier property (thanks to @gitlost)
    Updated and improved android wrapper (thanks to @markusfisch)

Worth mentioning:

    Most deprecated APIs from last release were removed (will likely
    break your build if you still have deprecation warnings with
    1.2.0)
    New Result::lineCount and DecodeHints::minLineCount properties
    to improve reliability of 1D code reading
    New Result::isMirrored property (works for QRCode, PDF417,
    DataMatrix)
    Improved FNC1 handling and deprecation of DecodeHints::assumeGS1
    Lots of small fixes all over the place
    Drop in-tree copy of stb image library
    New OpenCV example code
    QRCode reading improvements
    Python 3.10 support

graphics/zxing-cpp: import zxing-cpp-1.2.0

ZXing-C++ ("zebra crossing") is an open-source, multi-format 1D/2D
barcode image processing library implemented in C++.

It was originally ported from the Java ZXing Library but has been
developed further and now includes many improvements in terms of
quality and performance. It can both read and write barcodes in a
number of formats.
