Port to CMake from qmake, and split decoder into subdirectory
Qt 5 has had to be dropped as CMakeLists.txt uses qt_* specific commands which are implemented in Qt 6 onwards. cmake --install is only working on Linux at the moment; it installs the executable and the bundled example tti files into /usr/local/share/doc The teletext decoder with its document storage has been moved to a subdirectory with the intention of making it possible to use in other projects, but some further separation of editing stuff will be needed.
