Lazy focus mode

[dicash]

What problem you are trying to solve?

We're using imask as part of mui-like input component, it has placeholder displayed by default, and upon click moves it up and shows currency input.

We'd like to use imask lazy=false to display dollar sign when input is focused, and use lazy=true when it's not.

Describe the solution you'd like

We'd like to have lazy='focus' mode, that enables lazy mode only when the input is focused, and can display native placeholder otherwise.

Describe alternatives you've considered

We considered exposing imask instance via imperative handle to parent component with manual control of onfocus/onblur, but we preserve ref for external form validator so we cannot use it unfortunately.
