SDR++ iak v1.2.2-alpha3

Added

• Merged KiwiSDR support from SDRPlusPlusBrown by @sannysanoff.

Changed

• Further steps to fork from upstream with iak branding so that the iak fork could live side by side with upstream SDR++ on the same system. Fixed Linux Debian packages broken by previous iakization.
• Fix of default audio sink on Linux with ALSA audio API selected: Don't let the ALSA audio queue dry up if radio is stopped. The ALSA sink would not restart if the radio was paused and restarted.

SDR++ v1.2.2-alpha2

Changed

• Reworked high DPI display handling: The display DPI is newly respected.
• A new user display scaling factor now multiplies with the display native DPI scale.
• General clean-up of the UI scaling code to respect the display and user scaling factors.
• Expanded the touch region around the view splitters on Android so that they could be touched by thick fingers.

SDR++ v1.2.2-alpha1

Added

• Added Android audio rerouting when the preferred audio output changes.
• Added Ctrl+scroll waterfall bandwidth zooming.
• Added initial Android multi-touch support for waterfall zooming.

Changed

• Updated CI artifact naming to include version information, commit distance, and commit hash from git describe.
• Added the -iak infix to release artifact names and to Linux Debian package naming to keep this fork isolated from upstream SDR++ packages.
• Reworked CI release handling to read version information from version.h.

Fixed

• Fixed Android audio sink behavior by pausing and restarting audio output to work around devices that lock when the audio queue dries up.
