Fixed some test programs, tried to fix test_hyperseti.py

As a warm-up for exploring the possibility of producing a dat-writer for the turbo_seti pipeline code, I tried out the test programs which used to work ok.

Modified:

• hyperseti/dedoppler.py - looking in the wrong place for apply_boxcar
• test/test_data_array.py - modest change just so that I could run it with Python as opposed to using pytest due to some environment trouble with pytest (sql database locked??)
• test/test_datwrapper.py - expected length of arrays
• test/test_kurtosis.py - sk_flag calls missing the metadata parameter

Did not come to a conclusion but modified:

• test/test_hyperseti.py

Might be ok but I inserted print-debug statements while wrestling with test_hyperseti.py:

• hyperseti/hits.py - might need some defensive code to prevent crashes on poor input.

New approach.
