[WIP] Add Solana Web3.js 2.0

[amilz]

• Creates a Solana Client Factory that allows creation of a client using v1 or v2 of Solana Web3.js following a standard interface
• Deprecated existing Solana Class (leaving this exposed for now with warning)

TODO:

• Code Review
• Tests

Sample Use:

import { ClientVersion, SolanaClientFactory } from './solana';
import { getAddMemoInstruction } from "@solana-program/memo";
import { getTransferSolInstruction } from "@solana-program/system";
import { createKeyPairSignerFromBytes, lamports } from "@solana/web3.js-v2";

const solanaV2client = SolanaClientFactory.createClient(ClientVersion.V2, {
  endpointUrl: 'https://example-endpoint.com',
  wssEndpointUrl: 'wss://example-endpoint.com',
});

async function sendTransaction() {
    const payerSigner = await createKeyPairSignerFromBytes(new Uint8Array([0,0,0...0,0,0]));

    const instructions = [
        getAddMemoInstruction({
            memo: "QN SDK Live on v2!",
        }),
        getTransferSolInstruction({
            amount: lamports(BigInt(1)),
            source: payerSigner,
            destination: payerSigner.address, // use payerSigner.address for demo purposes
        })
    ];

    const signature = await solanaV2client.sendSmartTransaction({
        instructions,
        signer: payerSigner,
    });

    console.log(`Transaction sent! Signature: ${signature}`);
}

sendTransaction().catch((error) => {
    console.error(`❌ Error: ${error}`);
    process.exit(1);
});
