/** Our microcontroller we have laying around only has 4 hardware pwm channels.
 * Because we want 8, we will create software PWM as an alternative.
 *
 * Notes to self to forcast nessessary optimizations (translates to color accuracy): 
 *  Our error margin is 1/255th (13us at pwm freq 300hz) of a cycle. 
 *  Cycles until next channel could be triggered:
 *    209 at 16Mhz
 *    130 at 10Mhz (have one available)
 *    104 at 8Mhz
 *    13 at 1Mhz (have one available)
 *
 * To decrease the amount of cycles every pwm timer interrupt, we'll generate the 
 *
 * We might also want to make sure these values aren't updated every loop
 *  from random noise coming from the potentiometer. Test without, decide then.
