Exposes NodeComponentProps

[jdmg94]

This type needs to be exposed in order to properly type custom node components, see issue #81

[gregjoeval]

also as a work-around, I believe this is the equivalent type for anyone wondering

import { ListChildComponentProps } from 'react-window';
import { NodePublicState } from 'react-vtree/dist/es/Tree';

type ITreeWalkerData = {
 // This is your data model
}

type TreeNodeComponentProps = ListChildComponentProps<ITreeWalkerData> & NodePublicState<ITreeWalkerData>;
