warn if fft_len-2 % FFT_WIDT != 0
typo in warning output: fft_len-2
print frame timing
increase FREQ_MAX. also increases fps -> less time for the flipdot update (~0.5ms per OE pulse)
print frame timings in verbose output
added more timing measurements
lazy fail: use tv.tv_sec, too
timing measurements: sum flipdot timing over the whole frame
added VERBOSE_FULL. VERBOSE now displays only timing, not the full chart
newline in verbose output
added bargraph to verbose output
