1.2.0-rc1

New features:

• Universal binaries for Mac ARM and x86 computers.
• qFlipper can now be built with either Qt5 or Qt6. Static linkage is also supported.
• MacOS builds now use Qt6. Qt6-based builds for other systems are under way.
• The "Install from file" action now supports .tgz firmware update bundles.
• [FL-2796] Internal memory backups are now saved as .tgz files, which is a lot more intuitive.
• [FL-2756] The last folder visited in the file picker dialog is now saved.

Bug fixes:

• [FL-2754] Improve the progress display when a lot of small files is uploaded in the file manager.
• [FL-2755] The file manager window updates only once when all file operations are finished.
• The minimise button is now working on MacOS.
• Usual typo and small bug fixes.

Known problems:

• Due to some Qt6-related regressions, it is now possible to drag the application window by the titlebar area only.
• Qt6 spams thousands of linker warnings on MacOS. This is an upstream bug which will be fixed in Qt 6.4.
