Orphan instances

Description

Orphan instances allowing generic deriving of Group instances:

> data MyRecord
>   = MyRecord
>   { field1 :: Sum Double
>   , field2 :: Product Double
>   , field3 :: ( Sum Int, Sum Int )
>   }
>   deriving Generic
>   deriving ( Semigroup, Monoid, Group )
>     via GenericProduct MyRecord

Also includes some instances for newtypes from base such as Identity and Const.
