Cannot inherit from PinCodeTextField

[alexruden]

Want to create my class, based on your:

class MYPinCodeTextField: PinCodeTextField {
}

But got error
Cannot inherit from non-open class 'PinCodeTextField' outside of its defining module

As I understood, you need to declare as open class instead public
@IBDesignable public class PinCodeTextField: UIView ->
@IBDesignable open class PinCodeTextField: UIView

Thank you!

Sure, could you please open the PR with this changes? I'm a little bit busy so can't do this in the nearest future
