feat: web worker for image to pdf processing #101
Description
Problem Statement
The application freezes when executing the downloadImagesAsPdf function, which involves heavy computation for image processing and PDF generation. This occurs due to the execution of resource-intensive tasks on the main thread, leading to a degradation in UI responsiveness.
Expected Behavior
The application should maintain a responsive user interface even during resource-intensive tasks, such as image processing and PDF generation.
Proposed Solution
To address the freezing issue, we propose moving the heavy computation to a Web Worker, which runs in the background and doesn't block the main thread. The Web Worker will handle image processing and PDF generation asynchronously.
