v2.0.0

The most visible change from the client perspective is the removal of all formerly deprecated API, (almost) completing the 'cleanup'. Since I was way too slow with this release to implement a 'cleanish' SemVer release as discussed in #333, I decided to release this 2.0 with SONAME 3. A 3.0 release might bring the major version number back in sync with the SONAME.

Major Changes

• switch to UTF8 based API and remove deprecated UTF16 one (Result::text())
• remove all API deprecated in 1.4
• Adding a wrapper for iOS by @parallaxe in #337
• new Aztec detector implementation to support arbitrary rotation and position of the symbol
• support multi-symbol detection in Aztec detector
• replace all Qt originated ECI/CharacterSet conversion code with a new implementation provided by @gitlost (libzueci)
• require c++17 to build library and client code
• new DecodeHints::textMode() and Result::text(TextMode) API to specify how bytes are rendered into text.
• HRI (human readable interpretation) is the new default for the TextMode (has been for most cases before, but not all)
• new DecodeHits::tryInvert() feature to test for inverted symbols (white on black background)

Minor Changes

• deprecate TextUtfEncoding helpers, not required anymore with UTF8 APIs for both reader and writer
• support for multi-symbol and arbitrary position detection of DataMatrix symbols when library is built with c++20
• Include version number of QR Code and DataMatrix in Result by @markusfisch in #396
• reduce size of Result struct by about a third
• cleanup all license related files (see removal of the Qt code above)
• update links and comments to refer to new github.com/zxing-cpp/zxing-cpp home
• improved Code128 decoder for over/underexposed images
• support python 3.11
• a whole bunch of fixes and minor improvements all over the place
