Add support for plugin presets

Add support for plugin presets

Thanks to @srcejon this implements issue #1430 from a while ago.

This allows Presets to be saved / loaded for individual Devices, Channels and Features, via the new Star button in the basic settings dialog. E.g:

or

It should basically work the same as the existing Device Set and Feature Set presets, except that the preset only applies to a single Device, Channel or Feature.

If a preset is saved with Group/Description as Defaults/Default, then it will be loaded automatically whenever a plugin of that particular type is created.

vkFFT support

vkFFT support

Thanks to PR #1779 from @srcejon this implements #1166 by adding support for running FFT on GPU using the VkFFT library, with either Vulkan or CUDA backend,

To allow easier performance comparisons, the FFTEngine and FFTFactory class have been updated to support multiple simultaneous FFTEngines, so a user can switch between FFTW, Kiss and VkFFT at run-time via a GUI option (Preferences > FFT). Also, different bits of SDRangel can request different FFTEngines. So FFTW could be used generally, but a specific plugin could request VkFFT if it thinks it will benefit from it.

Also a simple profiler has been added, that displays average execution time in a dialog (View > Profile Data...). Profiling is enabled via the cmake -DENABLE_PROFILER=ON option. It is disabled by default, and when disabled, there should be no performance impact as the profiling code is not included in the executable. It can also be used to easily profile other parts of SDRangel - here showing GL spectrum draw time, as well as FFT. To profille some code, you just need to stick the PROFILE_START() and PROFILE_STOP("name") macros around the code.

Whether VkFFT uses Vulkan or CUDA is a cmake option, -DVKFFT_BACKEND=0 for Vulkan and -DVKFFT_BACKEND=1 for CUDA. The code should compile without VkFFT if neither the Vulkan or CUDA SDKs are available.

On Windows, VkFFT is automatically downloaded as an external project. If external project is off, then it can be downloaded with:

cd /opt/build
git clone https://github.com/DTolm/VkFFT.git
cd VkFFT
git checkout v1.3.1

It's a header only library, so doesn't need to be built.

Either the Vulkan or CUDA SDKs need to be installed to compile it:

Linux Vulkan Setup

cd /opt/install
mkdir -p vulkansdk
cd vulkansdk
wget https://vulkan.lunarg.com/sdk/download/1.3.250.1/linux/vulkansdk-linux-x86_64-1.3.250.1.tar.gz
tar xf vulkansdk-linux-x86_64-1.3.250.1.tar.gz
source /opt/install/vulkansdk/1.3.250.1/setup-env.sh
...
cmake -DVKFFT_INCLUDE_DIR=/opt/build/VkFFT/vkFFT/ -DVKFFT_BACKEND=0 ..

Linux CUDA setup

Install CUDA toolkit from https://developer.nvidia.com/cuda-downloads
export PATH=/usr/local/cuda/bin:$PATH
...
cmake -DVKFFT_INCLUDE_DIR=/opt/build/VkFFT/vkFFT/ -DVKFFT_BACKEND=1 ..

Windows Vulkan Setup

Install Vulkan SDK (With optional 64-bit Debug libraries) from https://vulkan.lunarg.com/sdk/home#windows
Copy include\glslang\Include\glslang_c_interface. and include\glslang\Include\glslang_c_shader_types.h from Linux SDK as they are missing (See https://vulkan.lunarg.com/issue/view/63d158a85df11200d569b2ab)
set VULKAN_SDK=C:\VulkanSDK\1.3.250.1  (or where ever you installed it)
cmake -DVKFFT_BACKEND=0 ..

Windows CUDA Setup

Install CUDA toolkit from https://developer.nvidia.com/cuda-downloads (This creates CUDA_PATH environment variable)
cmake -DVKFFT_BACKEND=1 ..

Unfortunately, in many cases, using the GPU (via either Vulkan or CUDA) is much slower than using FFTW, due to the overhead of getting the data from the CPU to the GPU. It may be more beneficial on embedded SoCs that have unified memory and relatively slower CPUs, but this has not been tried. So there's no reason to try to enable this in the release builds now, but it's the first step towards GPU support.

Audio CAT SISO plugin

Audio CAT SISO plugin

This MIMO plugin gets its samples from an audio device on the Rx side and sends its samples to an audio device on the Tx side. It is single stream on both Rx and Tx therefore it has "SISO" in the name. In addition it allows CAT control of a radio device using Hamlib. For now this is available only in Linux we'll see later how we can implement the Hamlib dependency in Windows. More details here

New plugins

New DSC demod plugin

Thanks to @srcejon this plugin demodulates and displays DSC messages used in maritime traffic. More details here

New Aaronia RTSA Tx plugin

This plugin allows sending I/Q samples to a HTTP server connected to a IQ modulator and Spectran V6 Tx input in the RTSA Suite. This makes it possible to use a Spectran V6 analyzer with Tx as a transmitting device. More details here. For now it is not possible to use it during extensive periods (~30mn max) before the clocks drift too much and the Tx xtops working correctly. Aaronia is working on a more reliable solution and this plugin will be adapted to it in the future.

Aaronia RTSA Rx support

Aaronia RTSA Rx support

New sample source plugin to support reception with the Aaronia RTSA (Real Time Spectrum Analyzer) and the Aaronia RTSA Suite software.
