* feat: make `ConstGeneric` fields public

Also make `ident` function public, but as a `&` instead of a clone.

* update comment

* Enable multiple calls to `modify_generic_constraints`

* get_or_insert_with

* Treat empty struct fields differently to a unit

A Struct { } should have Some(Fields::Struct(vec![])) rather than None.

This partially reverts cfb17c0 (#45)

* Add extra checks in test_enum_body_take()

New tests for empty struct members, and test Fields::names()

* Add `const` to inherent `impl` and attr support

* clippy and fmt

* GenConst: moved into gen_const.rs
- make_pub added
- Impl.generate_const added

* removed wrong comment
