Add custom icon for checkbox component

[tux2nicolae]

We use MaterialIcons in our app instead of MaterialComunityIcons and we have a problem with the checkbox not having a property for specifying a custom icon

p.s Sorry for opening again, I've rebased the branch and it seems that in the process the old PR was automatically closed

+1 I am using lucide icon, it's not rendering the icon and says

Tried to use the icon 'check' in a component from 'react-native-paper', but none of the required icon libraries are installed. To fix this, please install one of the following:
- @expo/vector-icons
- @react-native-vector-icons/material-design-icons
- react-native-vector-icons

You can also use another method to specify icon: https://callstack.github.io/react-native-paper/docs/guides/icons Error Stack:
    at overrideMethod 

I have configured the custom icons in the paper provider settings, yet just this icon isn't showingup!
