Array.from isn't faster than the spread element

[fregante]

The readme says:

Use Array.from instead of [...iterable] for performance benefits.

but it doesn't appear to be correct.

Array.from is just different in that it works on array-like objects, but it's actually ever-so-slightly slower in all browsers I tested.

At the time I had initially written the rule there was a performance benefit in some browser, though it is probably a good point to remove that now. It is after all just a style choice at this point (apart from the slight difference in behavior of the mapping function with typed arrays)
