Solana keypair 3 - Saving the keypair locally. Using 'fs' from 'node'.

Description

I will be exploring some simple ideas on the Solana Development pathway, that may be useful for a beginner who is trying to follow Solana Bootcamp 2023/2024. Those tutorials are great but they move to quick between some basic topics, say Keypair generation and Multi-instruction transactions. I'll be covering in this video series things that may help beginners and act as fillers between the Bootcamp projects. Github: https://github.com/rohaan-sahu/solana-keypair-basics
