Generic really kills time, sadly Print and JSON all depend on it, I’ll try to split instances first.

We may have to wait for GHC to improve the compilation speed of Generics:
https://gitlab.haskell.org/ghc/ghc/-/issues/5642

Most of the compilation time is spent on simplify generic's instance method.
