Formatted 2b5c6592df fix: three utility bugs in compare, LUT, and triangular waveform scripts ...

- compare.py: capture max_abs_error return values and add pass/fail
  check (was silently discarded, missing outlier detection)
- LUT.py: replace no-op pass with actual print of 8-bit Verilog values
- Gen_Triangular.py: fix plt.plot(2*n, y) -> plt.plot(t, x) scalar vs
  array bug that produced broken time-domain plot
