Splits astral symbol into surrogate pairs

[Eric Eastwood]

The polyfill splits each unicode character(astral symbol) into their surrogate pairs while the native implementation keeps them intact.

var arrayFrom = require('array.from');

// ["🖐", "🏿"]
const nativeResult = Array.from('🖐🏿');
// ["�", "�", "�", "�"]
const polyfillResult = arrayFrom('🖐🏿');
console.log(nativeResult, polyfillResult);

This works with the latest from the repo.

I suspect #33 fixed things up. Thanks @falsandtru 😀

@ljharb Friendly ping for timeline/todos on next npm release?

[Jordan Harband]

There's a bit of work to do before the master branch is ready for release. It likely won't be super soon.

[Jordan Harband]

v1.1.0 is now released which should contain all the latest fixes, and will iterate properly in every version of every engine.
