Parallel loading on mli load

[5ouma]

✏️ Describe the feature

mli load takes a long time if there are many Login Items in login_items.json because Add() just loops the Login Items array ([]*loginItem).
So it should load parallelly to speed up.

mli/lib/oascript.go

Lines 46 to 59 in fd914ba

	func (loginItems *LoginItems) Add() error {
	for _, loginItem := range *loginItems {
	if isExist, err := isExist(loginItem.Path); !isExist && err == nil {
	fmt.Printf("⚠️ not found: \"%s\"\n", loginItem.Path)
	continue
	}
	if _, err := mack.Tell("System Events", fmt.Sprintf(`make login item at end with properties { name: "%s", path: "%s", hidden: %v }`, loginItem.Name, loginItem.Path, loginItem.Hidden)); err != nil {
	return err
	}
	fmt.Printf("🔍 %s\n", loginItem.Name)
	}
	return nil
	}
