Teach synth optional args to take prefixed maps:

* Synth args can now take one or more maps at the 
  start of the args (before it breaks into kv pairs)

i.e

play 50, {amp: 0.5}, {release: 2}, amp: 2

This allows for named arg settings to be mixed in:

perc = {attack: 0, sustain: 0, release: 0.1}
play 50, perc

or even functions generating named args:

define :perc do |attack, release|
  {attack: attack, sustain: 0, release: release}
end

play 50, perc(0, 0.1)
