Validate 'aud' in DID Token

[magic-ravi]

📦 Pull Request

• Add Admin SDK support for Magic Connect
• Validate aud in DID Token against the client ID associated with the secret key.
• Pull client ID from Magic servers using secret key if not present.
• Skip validation of attachments if the string 'none' is passed. (This will make it easier for 3rd Party wallets (like Metamask) to sign DID tokens.

🚨 Test instructions

1. yarn build && npm link
2. In new repo run npm link @magic-sdk/admin@1.10.0

const { Magic } = require('@magic-sdk/admin');

const maSecretKey = "";
const mcSecretKey = "";
const maClientId = "";

const DIDT = "";

async function exec() {
    const magicAuth = await Magic.init(maSecretKey);
   magicAuth.token.validate(DIDT);
    console.log("MA Token validated.")
    const metadataResult = await magicAuth.users.getMetadataByToken(DIDT);
    console.log(metadataResult);

   // old constructor way
   const oldMagicAuth = new Magic(maSecretKey);
   oldMagicAuth.token.validate(DIDT);
   console.log(oldMagicAuth.users.getMetadataByToken(DIDT));

    const magicConnect = await Magic.init(mcSecretKey);
    // Should fail
    try {
        await magicConnect.token.validate(DIDT);
    } catch (e) {
       console.log(e);
    }
    try {
        await magicConnect.users.getMetadataByToken(DIDT);
    } catch (e) {
        console.log(e);
    }

    const magicConnectWithClient = await Magic.init(mcSecretKey, {clientId: maClientId});
    await magicConnectWithClient.token.validate(DIDT);
    console.log("MC Token validated with MA client ID.");
