Updated to build with gnuradio 3.10 and pas all tests.

Thanks for the work @maitbot! I was just about to start doing this myself. In the process of building and installing, I did find that. in the GRC files for each block, I needed to update:

templates:
  imports: import radar

to:

templates:
  imports: from gnuradio import radar

for each GRC block definition.

I also found that the following was needed for my build:

• #include <qwt_text.h> to lib/scatter_plot.h
• #include <qwt_text.h> tolib/time_plot.h
• #include <qwt_interval.h> to lib/spectrogram_plot.h

Other than that, almost tests are passing for me with python=3.10.2 and gnuradio=3.10.1.1. The only failing test is for ts_fft_cc which seems to be a slight numerical difference between fftw3 and numpy.fft in calculating the FFT (FFTW3 vs PocketFFT). Relaxing https://github.com/maitbot/gr-radar/blob/4e80df4b281d8305e79113f360347edf3f9bb13a/python/radar/qa_ts_fft_cc.py#L53 to 3 decimal places solved this for me. I think we can ignore that problem.

Other than that, I will go through the examples and make sure everything is working for me! 🐱‍👤

Can't build GR 3.10 on my laptop right now. @MLsmd, would it be possible that you try building this branch?

Build completed on 3.10.4 w/ 22.04 python version. However, the one flow graph I opened under examples (examples/simulation/simulator_fmcw_rcs.grc) tossed up just a couple complaints before opening and then I got a module import of 'radar' not found.

I also had to git checkout the mait/gr-3.10 branch as the default mait-3.10 branch linked above would not built, stopping at GrSwig not found.
