Use a single spritesheet instead of individual image requests for network logos

[sossargsyan]

• Updated the current implementation of network logos to use a single spritesheet instead of individual image requests.
• Modified the codebase to extract and display logos from the spritesheet.

Notes:

• The spritesheet generator can be found in the this repository.
• The GitHub action is triggered when a new commit is pushed to the main branch.
• The generator script creates a spritesheet image and metadata.json file based on the logo images in the logos folder.
• The GitHub action then uploads the generated spritesheet and metadata.json to an AWS S3 bucket for public access.
