Add typescript support

[s6nqou]

1. Added TypeScript support for the package.
2. Declared types for RPC methods based on the Jito official documentation.
3. Renamed index.js to index.ts and added type annotations to the file.
4. Introduced the enableConsoleLog method to prevent console.log and console.error outputs in the production environment.
5. Removed the dist folder and added a prepublish script to generate javascript and type declaration files before publishing. The published package will now include only the dist folder.
