devel/hs-newtype-generics: import hs-newtype-generics-0.6.2

Per Conor McBride, the Newtype typeclass represents the packing and
unpacking of a newtype, and allows you to operate under that newtype with
functions such as ala. Generics support was added in version 0.4, making
this package a full replacement for the original newtype package, and a
better alternative to newtype-th.
