Rewrite plugin: iterate through values to rewrite

Array replacing is now supported.

If the source data is:

[
  'name' => [
    'foo',
    'bar',
    'qux',
  ],
  'ext' => [
    'jpg',
    'png',
    'gif',
  ],
]

And you apply a the Rewrite plugin to the source 'name' using the text [name].[ext]

You will get:

[
  'name' => [
    'foo.jpg',
    'bar.png',
    'qux.gif',
  ],
  'ext' => [
    'jpg',
    'png',
    'gif',
  ],
]

I've also been working on supporting nested data, if you use the text [name].[ext.1] instead, you should get:

[
  'name' => [
    'foo.png',
    'bar.png',
    'qux.png',
  ],
  'ext' => [
    'jpg',
    'png',
    'gif',
  ],
]

For this I've not added test coverage yet. Marking as "needs work" for additional test coverage.

Thanks for your review! I did not notice it earlier, since the issue did not get updated.

I merged the code!
