V3.0.1

[tomneda]

AppImage of DABstar V3.0.1, based on Ubuntu 20.04, tested on Ubuntu 24.04.

I made big changes on the mainline, including the upgrade from Qt 5 to Qt 6.
So, I decided to raise the major version to 3.

• Upgrading from Qt 5.x.x to Qt 6.7.3. So, using also the new QWT 6.3.0 for that.
• The course frequency correction got much better due the proposal from old-dab.
• Audio output is fixed done with QtAudio, not more with portaudio, some parts taken from AbracaDABra (https://github.com/KejPi/AbracaDABra) and adapted it largely.
  Stuttering while sound startup after service change is away (with soft fade-in/fade-out).
• Use new RTL-SDR driver access from old-dab (https://github.com/old-dab/rtlsdr).
• Use current SDRPlay driver access V3.15 with adaptions from old-dab (https://github.com/old-dab).
• Issue "Service Label change" fixed (Service Label change #23).
• For the service list the non-audio services can be now suppressed not to be shown there (selectable).
• While playing files, not anymore a wrong channel number is shown in service list. Instead "File" is shown there.
• Provide stereo peak-level meter on main widget.
• The audio buffer state is shown on main widget.
• Email addresses and links are clickable on dynamic label text (selectable).
• A compass direction (NW, NNE, NE, ENE, ...) is shown at the transmitter location line.
• Fix in scaling of EVM(dB) in carrier scope.
• Minor and major refactorings on different parts.

Still known problems:

• The audio buffer got a underflow after a while at service with certain bitrate like 104 kBit/s.
• At first startup the audio output destination is maybe not the intended.
• Minor other things (stored on my private TODO list)
