TreeNode Generic

Currently TreeNode does not accept a generic for its value prop.
So the value is always type string | number.

However TreeSelect accepts a generic and defaults the type to DefaultValueType (RawValueType or RawValueType[])

I'd expect the following generic to work

type MyCustomValueType = "yes" | "no";

class App extends React.Component {
  render() {
    return (
      <TreeSelect<MyCustomValueType>>
        <TreeNode<MyCustomValueType> value="yes" title="yes" />
        <TreeNode<MyCustomValueType> value="no" title="no" />
        <TreeNode<MyCustomValueType> value="ts error" title="no" /> {/* Throws TS error */}
      </TreeSelect>
    );
  }
}

Start with the TreeNode definition in src/TreeNode.tsx and compare its value prop with the generic handling in src/TreeSelect.tsx around line 613. Check how the provided TypeScript example is typed, including the invalid "ts error" value. Done means custom TreeNode and TreeSelect generics accept valid values and reject invalid ones.
