[FEATURE] Randomised Generic Metadata Images

[thepeanutgalleryandco]

Summary

Add the ability to provide a list of ipfs urls that can be used in the generation of generic metadata.

Basic example

Provide an array of IPFS URLs in the nft_details.js configuration file.

['https://ipfs.io/ipfs/bafkreigye3xz72jp2eskhrgq4blhh5ec3wwbj4isqejv4a6mdhqzcuvquy', 'https://ipfs.io/ipfs/bafkreigye3xz72jp2eskhrgq4blhh5ec3wwbj4isqejv4a6mdhqzcuvqu2', 'https://ipfs.io/ipfs/bafkreigye3xz72jp2eskhrgq4blhh5ec3wwbj4isqejv4a6mdhqzcuvqu3'] ;

Modify the "update_json_to_generic_meta.js" script to look at this URL list and then randomly choose one of the URLs and assign it to the generic JSON metadata.

Motivation

This will allow users to have different generic metadata images instead of a single generic metadata image before their reveal.

Updated the constants/nft_details.js genericURL field from a single key:value field to a key:array field. The updated field name is now called genericURLs.
"genericURLs: ["GENERIC_URL_#1_HERE", "GENERIC_URL_#2_HERE", "GENERIC_URL_XXX_HERE"]"

Users can now simply add a list of IPFS URLs of the images that they have manually uploaded, to the genericURLs array and when the "update_json_to_generic_meta.js" script is used, it will randomly pick one of the URLs in this array and assign it to the edition. If the user only wants a single generic image, then they can simply put the single url in there.

For example:

• 1 generic URL - genericURLs: ["https://ipfs.io/ipfs/bafybeifipag6zgekhcczypcsv4qqvoul6yobw22f3ga3hetoaqinn2xova"]

• 2 generic URLs - genericURLs: ["https://ipfs.io/ipfs/bafybeifipag6zgekhcczypcsv4qqvoul6yobw22f3ga3hetoaqinn2xova", "https://ipfs.io/ipfs/bafkreic7glqatx6lzay2hl2xn5n5p75f4njobiza5ianuryvjhgauckh2m"]

• 3 generic URLs - genericURLs: ["https://ipfs.io/ipfs/bafybeifipag6zgekhcczypcsv4qqvoul6yobw22f3ga3hetoaqinn2xova", "https://ipfs.io/ipfs/bafkreic7glqatx6lzay2hl2xn5n5p75f4njobiza5ianuryvjhgauckh2m", "https://ipfs.io/ipfs/bafkreihabbil5ueqrn4fvfvoywmzrvk7jgcioza7svulj4vfxphrkuzgfu"]
