Android currently fails for unicode strings that contain international characters. Added test-case with 'T\xf8nsberg' as example on FIX-unicode branch. Tests pass on iOS. /cc @demetris-manikas

Some derivation results for p=10 N=2^18 on a Galaxy S8:

21.820 21.933 seconds with plugins.scrypt

23.577 22.672 with scrypt-async-js (nice job @dchest)

I will do more tests yet... it's weird that a native lib is barely faster than a pure JS lib. I was wondering is there anything on top of your head that can be optimized to deal with p more smoothly, like run derivation in parallel?

This is cross platform code used:

function derive(password, email, cb){
  var opts = {
    N: Math.pow(2,18),
    interruptStep: 0,
    p: 10,
    r: 8,
    dkLen: 32,
    encoding: 'base64'
  }

  if(E){
    nodeRequire("scrypt").hash(password,opts,32,email).then(function(root){cb(root.toString("base64"))})
  }else if(window.plugins && window.plugins.scrypt){
    window.plugins.scrypt(function(root){cb(hexToBase64(root));}, alert, password, email, opts)
  }else{
    setTimeout(function(){ //interrupt step prevents animation
      scryptjs(password, email, opts, cb)
    },0)
  }
}

hex returned is not equal one from node's scrypt or scrypt-async-js libs, for default or any other opts https://gist.github.com/homakov/a3d9ae0a2d83b45e25cc297030dd5522

Is there any example that would return same value for the above libraries and for this plugin? I simply pass password/salt as bare strings UTF8 encoded
