Add Device Motion module

[nkymut]

This change adds 'motion' package, which introduces smartphone's acceleration, gravity, rotation, and orientation signals for dynamic pattern creation in Strudel.

example:

enableMotion() //enable DeviceMotion 

let tempo = 200

$_: accX.segment(16).gain().log()

$:n("[0 1 3 1 5 4]/4")
  .scale("Bb:lydian")
  .sometimesBy(0.5,sub(note(12)))
  .lpf(gravityY.range(20,1000))
  .lpq(gravityZ.range(1,30))
  .lpenv(gravityX.range(2,2))
  .gain(oriX.range(0.2,0.8))
  .room(oriZ.range(0,0.5))
  .attack(oriY.range(0,0.3))
  .delay(rotG.range(0,1))
  .decay(rotA.range(0,1))
  .attack(rotB.range(0,0.1))
  .sound("sawtooth").cpm(tempo)

Tested only on the iPhone 13 Pro; testing on Android devices is still required.

sorry for not looking at this for so long.. thank you for the PR ! the code looks good, tho it seems the PR is now mixed with #1223 ?
i can test this on android as well..
it might also be useful to have a little guide in the docs so people can discover this feature

[nkymut]

Oops, I didn’t realise I had mixed this up with other updates I was testing.
I’ll try to roll back the commits where I published the PR and am also looking into the guide for the module.

[felixroos]

this also ready for merge?

[nkymut]

I have added minor details to the local SSL configuration steps,
and apart from that, I have nothing else to add on my end.

[felixroos]

same here, i'll test this soon :) thanks for your work

[felixroos]

i've fixed / tweaked some things, now it should be ready to go

Oh wow this looks awesome

[felixroos]

now deployed! tested it with android and it works! (without permission request for some reason)

thanks again @nkymut !
