Image Processing API

This Node.js API, built with TypeScript and Fastify, allows you to perform various image processing tasks. It leverages parallel computing, async/await, and promises to efficiently process images using the Sharp package. The API offers the following features:

1. Upload Files by URL: You can upload images from external URLs.

2. Upload Files via Direct Upload: You can also upload images directly to the API.

3. Apply Watermark: Apply watermarks to existing images.
