This patch is backwards-compatible.

This change refactors the Builder class to allow options in any order. This builds on #357 and solves one of the annoyances I had with the builder API (which I, unfortunately, introduced in #307), which is that it became order-dependent. This now has an internal data object that holds the info until everything is loaded.

The one exception to the order-dependent is still the .brand() method (this was a requirement prior to #307 too). So I added an optional brand?: string argument to the build() function to make it more idiomatic to specify the brand up front.

// old way -- still works!
const cli = build()
  .brand('mycli')
  // ...
  .create()

// new way -- documented
const cli = build('mycli')
  // ...
  .create()
