System.Process.Lens.CreateProcess

This module provides the associated optics and combinators for working with CreateProcess objects.

Because CreateProcess was created before the `_` prefix record name convention, some record accessors don't have an apparently "good" name for their corresponding lens. Those that do not are post-fixed with `_`. Thankfully, there are only 6 that meet the criteria: cmdspec_, env_, cwd_, stdin_, stdout_, and stderr_.

We provide classy variants of what we consider the significant portions of CreateProcess - namely, the std_in, std_out, and std_err entries.
