Multichain RPC / vrf Fetch

I find it extremely annoying to comb through the internet to find .env and config arguments for multichain development and testing. I want to just write a couple words in the command line and have my .env and helperhardhatconfig.js auto-created for me with the relevant parameters.

I used yargs to build a simple CLI, used Cheerio to parse RPC URLs from the pokt website. I couldn't quite figure out how to serialize the Chainlink VRF and pricefeeds from html to json (to then write into a config file) so I hardcoded the VRF configs. It was my first time working with Cheerio and Yargs so learning that was a cool process.

I hope that this accelerates multichain development on pokt!
