`pick` doesn't work for `with_items_range`

Given this setup I see 1000 requests rather than the expected 10.

          "foo": "{{ item }}",
        }
      headers:

    with_items_range:
      start: 1
      step: 1
      stop: 100
    shuffle: true
    pick: 1

Not very familiar with golang, but searching the code it looks to me like pick hasn't been implemented for with_items_range?

Happy to try my hand at a PR if that is the case.

I'm not very familiar with golang either. 😉 Whatever Rust pull request for a bugfix will be welcomed.

The coffee obviously hadn't taken effect yet :doh:. Will see what I can do.
