No support for optional enum fields

[RomanSter]

it seems like the lib does not know how to cast from enum optinal (pointer) fields.

command used to generate the proto:

protoc --go_out=./ --go-grpc_out=. --gorm_out=engine=postgres:./ user.proto

protoc verison:

libprotoc 3.20.3

proto example user.proto:

syntax = "proto3";

package user;

option go_package = "./user";
import "gorm.proto";

message User {
  option (gorm.opts).ormable = true;
  int32 id = 1;
  optional Gender gender = 2;
}

enum Gender {
  male = 0;
  female = 1;
}

One of the generated user.pb.gorm.go methods:

// ToPB runs the BeforeToPB hook if present, converts the fields of this
// object to PB format, runs the AfterToPB hook, then returns the PB object
func (m *UserORM) ToPB(ctx context.Context) (User, error) {
	to := User{}
	var err error
	if prehook, ok := interface{}(m).(UserWithBeforeToPB); ok {
		if err = prehook.BeforeToPB(ctx, &to); err != nil {
			return to, err
		}
	}
	to.Id = m.Id
	to.Gender = Gender(m.Gender)
	if posthook, ok := interface{}(m).(UserWithAfterToPB); ok {
		err = posthook.AfterToPB(ctx, &to)
	}
	return to, err
}

to.Gender = Gender(m.Gender)

causes "Cannot use '(Gender)(m. Gender)' (type Gender) as the type *Gender"

to fix this we need to cast it to a pointer Gender type like : to.Gender = (*Gender)(m.Gender)

right now I have to update the generated gorm file maualy each time I re-generate for new fields...
if there is a solution please let me know!
