Would be nice to be able to disable text input without "disabling" the underlying element entirely

[gausie]

At the moment disabled goes onto the div here:

https://github.com/lovasoa/react-contenteditable/blob/master/src/react-contenteditable.tsx#L50

as well as making it non-editable here:

https://github.com/lovasoa/react-contenteditable/blob/master/src/react-contenteditable.tsx#L57

I'd like to be able to do the latter and not the former in some cases
