What's new in this version:

New features and enhancements:
- MKVToolNix GUI: the user can now control where the job queue files & the preferences INI file are stored via environment variables. If set, the variable KVTOOLNIX_GUI_STATE_DIR` can point to a directory where the GUI stores both the job queue sub-directory and the preferences INI file. If you only want to relocate the preferences INI file, you can store the desired file name for the INI file in `MKVTOOLNIX_GUI_CONFIG_FILE`. Implements
- MKVToolNix GUI: when adding directories via drag & drop/copy & paste the GUI will now offer the user the option to create one multiplex settings tab per directory & adding all files from that directory to the corresponding, newly created tab.

Fixed:
- Mkvmerge: AV1 OBU parser: fixed identifying files that only contain single frame
- KVToolNix GUI: multiplexer: when reading color parameters from identified files that are floating point numbers (minimum/maximum luminance, projection pitch/roll/yaw) the numbers will be formatted in floating-point notation instead of scientific notation as mkvmerge only supports the former.
- MKVToolNix GUI: multiplexer: color parameters that are floating point numbers (minimum/maximum luminance, projection pitch/roll/yaw) will only be set to a value during identification if the identification actually contains the property, and not to 0 anymore if it doesn't.

Build system changes:
Several merge requests where accepted that improve compilation on MSYS2 on Windows. Note that this build type isn't supported.
