Missing TypeScript Typing

[loganknecht]

Hello!

I am very impressed with the work you've done with this project and its themes!

For typescript users, I am reporting that there are no type definitions.

The workaround is to create a react-sortable-tree-theme-minimal.d.ts file in the appropriate location. Mine was placed as a sibling file to my react app's App.tsx and index.tsx file.

Then just add this as the contents of the file:

declare module "react-sortable-tree-theme-minimal";

I may try to create the type definitions for this in the future as I'm interested in understanding that process.

Regardless, great work and keep it up!
