Calculate phaser modulation phase based on time

[daslyfe]

phaser no longer has to rely on orbits and free running lfos, because the phase of the modulator is calculated based on the time. the phaser should sound exactly the same as before

$: note("{f g g c d a a#}%8")
  .gain(1).s("sawtooth").lpenv(4).lpf(200).fanchor(0).lpdecay(.2).phaser(2)
  .attack(0)

$: note("{f g c d a a#}%1".sub(12))
  .gain(1).s("supersaw").lpenv(4).lpf(200).fanchor(0).lpdecay(3).phaser(3)
  .attack(0)
