Keep arrays as arrays #23

[Cirrusware]

Motivation and Context

In aggreement with the issue #23. We would like to keep modified arrays with the complete values instead of the difference object.

How Has This Been Tested?

Adding two test of the diff test suite. Including basic object which contains an array and with a nested object.

const a = {
  a : [1],
},


const b = {
  a : 1, 
  foo: {
    bar: [1]
  },
}
