Implement a utility helper class that ease dealing with Ethereum Signature and support something similar to `ethers.Signature.from({r, s, v} | string)` about web3.js

[Vishalll07]

hello sir,
sir are { r, s, v } signature variables generated from Externally Owned Accounts's private keys and used for digital signature creation and verification?

and are asking for a helper class sort of like this
class SignatureHelper { static from(input) { if (typeof input === 'string') { return this.fromString(input); } else if (typeof input === 'object' && input.r && input.s && input.v !== undefined) { return this.fromObject(input); } else { throw new Error('Invalid input format for Signature'); } }
