[Request] Add hash support for bn::type_id_t

[copyrat90]

hash for the bn::type_id_t is missing for some reason?

namespace bn {
    template <>
    struct hash<type_id_t> {
        [[nodiscard]] constexpr unsigned operator()(type_id_t value) const {
            return hash<unsigned>()(unsigned(value.internal_id()));
        }
    };
} // namespace bn
