The fake waveform generator functions, `fake_sawtooth()` and `fake_squarewave()`, called from `fake_waveform()`, have a `current_time` parameter which is the time since the start of a waveform period. The parameter value may be greater than the waveform period so they do a modulo operation to bring it into range. Do the modulo operations outside the functions in `waveform_ai_interrupt()` so that the waveform generator functions always get a `current_time` parameter less than the waveform period and do not have to do the modulo operation themselves. Also, only do the modulo operations when the time since the start of a waveform exceeds the waveform period. Usually, several samples are produced in each waveform period and modulo operations are typically more expensive than a simple comparison.
