Build failure with GHC 9.4 #57

Build is broken with GHC 9.4.1:

@Lysxia, see https://downloads.haskell.org/~ghc/9.4.1/docs/users_guide/9.4.1-notes.html#base-library

GHC.Generics now provides a set of newtypes, Generically and Generically1, for deriving generic instances via :lang-ext:DerivingVia. Generically instances include Semigroup and Monoid.

Thanks for the report. #58 should fix this. Will release over the week end.

Released: 1.0.0.0
