v4.0.1

Patches

• Revert to Node 6.x minimum support: 8c01d93
  The code works perfectly in that environment, so there's no reason not to.
  Truth be told, it was only bumped to 10.x because of the test runner constraint.

• (types) fix kleur/colors overloaded definition: f2f33a8
  Original print order assumed that every export returned null, which is not true.
