Adding types to mxgraph.

[aasimkhan30]

This PR integrates typings from typed-mxgraph(https://github.com/typed-mxgraph/typed-mxgraph) and updates the development workflow to better support TypeScript in the project.

Changes in this PR:

1. Type Definitions:

   • Added all mxgraph types to src/ts/mxtypings.

2. Project Structure:

   • TypeScript source files will now be in src/ts/.
   • The original mxgraph code remains in src/js/.

3. Recompiling Workflow:

   • After making changes to any code in src/js (original mx source), run yarn compile-mxgraph to compile mxgraph and update the typings in src/ts/mxtypings.

4. Bundling:

   • Added esbuild to bundle everything into a single file, ensuring compatibility with simple HTML examples.

5. Examples:

   • New TypeScript examples are now located in the examples-ts folder.

6. Updated Documentation:

   • The readme has been updated to include linting information and the new workflow.

• The error handling in the prependText function should be improved. The fs.close method should handle errors properly.

fs.close(fd, (err) => {
