Nft Collection Generator Versions Save

• Fixed an issue when using the forbidden array to exclude all options of a specific trait type.

• Script calculate-hash renamed to calculate-hashes.
• calculate-hashes script now calculates the SHA-256 hash of each previously generated image and saves them in JSON files.

• Fixed update-base-uri script: now it adds the string ".png" at the end of the string.
• Added create-gif and calculate-hash extra scripts.

• Updated the main script to use fs.writeFileSync instead of the async version of the same function.
• Added new npm script to update the images base URI inside all the generated metadata files by running npm run update-base-uri.

This project uses a list of pre-configured traits and image layers to generate a unique set of images and metadata files for a collection of NFTs. You would be able to create your own collection by updating the traits configuration and the image layers.
