Guarantee NonZero, NonMax have same Ord, Hash as underlying type

Make Hash impl for NonMax satisfy this property.
All other trait implementations already satisfied this.

Changed

• Officially guarantee that NonMax<T> and NonZero<T> implement Hash the same as T (zoxoyvnx)
• Similarly guarantee that NonMax<T> and NonZero<T> implement Ord the same as T (lzlwsrtp)
  • This has always been the case for both types.

Fixes

• The Hash impl for NonMax now behaves the same as the underlying type T. (ppmqkvzx)
  • This property has always been true of NonZero, but has not been true for NonMax
