What's new in this version:

New features and enhancements:
- mkvmerge, MKVToolNix GUI's multiplexer: added support for the Emphasis audio track header element via the `--audio-emphasis` option. It is also read from Matroska files
- mkvmerge: the options `--list-stereo-modes` and `--list-audio-emphasis` have been added to list all support numerical & textual values for the stereo-mode` & `--audio-emphasis` options
- mkvpropedit, MKVToolNix GUI's header editor: added support for the Emphasis audio track header element via the `emphasis` property
- MKVToolNix GUI: multiplexer: when the track properties are configured to be displayed in a tab widget below the files & tracks in the "Input" tab, the "Color information" tab will be laid out in two columns. This reduces the minimum height the whole tab widget requires. Implements #3401.
- MKVToolNix GUI: greatly sped up closing the preferences dialog by only re-running certain initialization functions when their corresponding settings have changed
- mkvinfo, MKVToolNix GUI's info tool: added support for the following new elements from Matroska v5: Emphasis audio track header element; Chapter Skip Type; Edition Display; Edition String; Edition Language IETF.
- mkvmerge, mkvpropedit: added support for the following new chapter elements from Matroska v5: Chapter Skip Type; Edition Display; Edition String; Edition Language IETF. The GUI's chapter editor will receive support for them in the next release.

Fixed:
- mkvmerge: Ogg/OGM reader: mkvmerge will now correctly skip tracks of unsupported types as well as tracks for which all track header pages haven't been found

Build system changes:
- libEBML 1.4.4 & libMatroska 1.7.1 are now required
- The bundled libEBML & libMatroska libraries were updated to v1.4.4 & v1.7.1 respectively
- The bundled `fmt` library was updated to v9.1.0
- The bundled `nlohmann-json` library was updated to v3.11.2
