Non-removable prefix

[milk-machine]

In some cases I need non-removable prefix. Add this feature, please :)

@milk-machine, how do you want to see a mask and a result of removing symbols?

Hey @milk-machine!
Thanks for your suggestion.

I'll keep this feature request, though I can't say this feature will come out soon. It's a little bit controversial, plus the implementation raises lots of design questions, including the one above by @CoolMind

yes this is very needed, ThnQ

Hi, @taflanidi is there any update?

P.S. As there is no official solution I would like to introduce a shortcut. Just override afterTextChanged method in MaskedTextChangedListener:

override fun afterTextChanged(edit: Editable?) {
    val text = field.text.toString()
    if (!text.startsWith(nonRemovePrefix)) {
        setText(nonRemovePrefix, field)
    } else {
        super.afterTextChanged(edit)
    }
}

I'll look into pulling this into the core, thank you so much!
