Add sample for dynamic amount of task.

[Kvaz1r]

It would be good (for copy-paste reason ;)) to have an example where amount of tasks is known at runtime and not compile time.

Please have a look at provided examples, whether the value comes from other function or is static doesn't rly matter. You can create worker pool dynamically during runtime same way its shown in this examples.
