Consistency checker verbose output is inconsistent with the actual tolerances evaluated

[snl-bconder]

Per the numpy documentation for np.isclose, the total tolerance of that function is equal to atol + rtol * abs(b)

SarPy calls the np.isclose method when doing approximations.

When the CPHD validator provides verbose output, the printed tolerances are incorrectly shown per the calculation in consistency.py:438.

This syndrome I observe is that tolerances are under-represented, and the representation shown for negative values will not account for rtol at all.

Good catch snl-bconder and thanks for the nice write-up. np.isclose has a weird history and we got bit by its odd definition here. We're working through a fix that makes the printout consistent with the checked arithmetic and will link the PR to this issue once it is posted.
