[Feature]: Use remote folder for screenshot comparision

[bitttttten]

🚀 Feature Request

We have a lot of screenshots in our app, and we'd like to instead use a remote storage to store our screenshots.

In theory we could load the remote image as a buffer, take a screenshot into a buffer, and compare buffers although we miss a lot of the DX with the screenshot comparison tool.

Example

No response

Motivation

The more images in our repo the slower it takes to clone and work on.

I was also looking for a similar solution and end up building one. refer to https://github.com/sudharsan-selvaraj/playshot

What it covers:

1. Support for Multiple Cloud Storage Options: Currently, the library supports uploading screenshots to Amazon S3 and SFTP servers. However, it can be easily adapted to work with other cloud storage providers.
2. Automatic Screenshot Upload: Screenshots are automatically uploaded to the remote server if there are test failures, eliminating the need to save them to version control.
3. Screenshot Updates: Users have the ability to individually update screenshots when there are changes in the UI.
4. Flexible Validation: The library provides methods for validating visual regressions for both entire pages and individual web elements.
5. Support for Soft Assertions: Built-in support for soft assertions is included, allowing the test suite to continue running even if a soft assertion fails, without interrupting the execution of subsequent test steps.
