Struct ocaml::custom::CustomOps

CustomOps duplicates sys::custom::custom_operations to provide a slightly nicer experience in Rust

This should rarely be constructed manually, custom! simplifies the process of creating custom types.

See the struct custom_operations section in the OCaml manual for more information about each field
