[WIP] [NO-MERGE] Adds WalletConnect adapter pkg

[gregsantos]

Adds a new package to wrap WalletConnect and expose SignClient and utils

This adapter/wrapper allows us to pin WalletConnect to a version for use with FCL. It exposes initWcAdapter and additional utils to consumers. Passing a projectId and optional metadata will initialize and return a SignClient for use in connecting to a Flow enabled WalletConnect wallet. This Adapter will be updated to support WalletConnect api and utils as needed.

EXPECT BREAKING CHANGES

This adapter can be passed to FCL config and used by the application and FCL to connect, authenticate, authorize, and sign messages.

Init adapter/client and add to config

import * as fcl from '@onflow/fcl'
import * as fclWC from '@onflow/fcl-wc'
import { initWcAdapter, getSdkError, QRCodeModal } from '@onflow/fcl-wc'

const wcAdapter = fclWC.initWcAdapter({
  projectId: WC_PROJECT_ID,
  metadata: {
    name: 'FCL WalletConnect',
    description: 'FCL DApp for WalletConnect',
    url: 'https://flow.com/',
    icons: ['https://avatars.githubusercontent.com/u/62387156?s=280&v=4']
  }
})

fcl
  .config()
  .put('wc.adapter', wcAdapter)

Get client from fcl.config

const { client, QRCodeModal } = await fcl.config.get('wc.adapter')

client.on('session_update', ({ topic, params }) => {
  const session = client.session.get(topic)
  console.log('EVENT', 'session_update', { topic, params, session })
})

await client.disconnect({
  topic: session.topic,
  reason: getSdkError('USER_DISCONNECTED')
})
