Support for handling Base64 image data in saveFile function

[debanshup]

I encountered an issue when trying to save base64-encoded images using the saveFile function. The current implementation doesn't handle base64 strings, and it raises an ENOENT error.

Feature Request

• Add support for saving base64-encoded image data directly in the saveFile function.
• This feature would allow users to pass base64 strings for images and ensure they are correctly decoded and saved as files.

Use Case

When parsing websites, images are often base64-encoded. This feature will streamline the process of saving these images without additional manual decoding steps.
