Add prefix/suffix for vue 3 support

Would be really cool. Waiting for this feature. Also documentaion is not very clear how we should pass currency props

[dm4t2]

With the upcoming major release, Vue Currency Input will no longer support custom prefixes or suffixes. Only currency ISO codes will be supported.

Why? It will be aligned back to its original purpose: the input of currency formatted numbers based on the ECMAScript Internationalization API. Currently, it just feels wrong to allow the component to behave like a pure number input by either omitting the display of the currency symbol (currency="null") or inserting custom ones (currency="{suffix: ' %'}").

in my opinion this is a great lack of flexibility
