Tools configuration of RichTextToolBar

[simoco0781]

Hi, is there any way to add/remove tools from the toolbar.
Or may it be possible to just add "superscript" and "subscript" pending the replacement by Slate.js?

Currently, there is no feature for adding/removing tools. If you are willing to provide a PR, we would be happy to accept it.

Perhaps it just needs to add more parameters, such as

 toolbar?: {
    prefix?: React.ReactNode;
    list?:  Array<'bold'|'italic'...>;
    subfix?: React.ReactNode;
  };
