Python3 incompatibility about pysdr

[kaklik]

Zároveň to vypadá, že pyfits už nepodporuje python pod verzi 3. Takže teď zřejmě nejde použít pysdr-recviewer s FITS soubory

Protože buď:

$ python2 pysdr-recviewer 20200809082529162_SVAKOV-R12_raws.fits 
Traceback (most recent call last):
  File "pysdr-recviewer", line 5, in <module>
    main()
  File "/home/kaklik/repos/bolidozor/pysdr/pysdr/recviewer.py", line 165, in main
    sample_rate, signal = read_file(sys.argv[1])
  File "/home/kaklik/repos/bolidozor/pysdr/pysdr/recviewer.py", line 144, in read_file
    import pyfits
ImportError: No module named pyfits

Nebo

$ python3 pysdr-recviewer 20200809082529162_SVAKOV-R12_raws.fits

While 3dwf.py should be Python 3 compatible, the remaining programs (pysdr-waterfall and -recviewer) don't seem to be. Reopening this issue.

I fixed all obvious Python3 incompatibilities. But unfortunately, there arose a mistake somewhere in the code, because the spectrum waterfall is twice as fast as the overlay. The result is that there are gaps between the spectrum texture every ten seconds.
