amaranth v1.5

• cleaned some silly stuff with storing the list in the quantizer, now it's even smaller
• no more envgen~, instead have a data envelope on the outside with custom time grain (default 1ms)
  • most times i just need a data envelope, instead of converting back from signal
  • it can be sample accurate with a 0.02 time grain and a vline~
  • sometimes don't need envelopes (or need many of them) so felt best to keep it outside and copy it as needed
• made the numbox ranges a bit bigger (for easier working with microtonal scales with more than 12 division)
• time grain input for the glide (and default to 1ms)
• allow a pulse width to [pd gate] (fun for working with fm models)
• kept that metro outside to remember that arpeggios are fun xD
