[fcl-wc] add pairing modal override and sessionRequestHook

[gregsantos]

• Improves deeplinking for pairing and requests on mobile and provides wcRequestHook for dApp to alert user of signing request
• Adds additional options to init for pairing modal override

import * as fcl from '@onflow/fcl'
import { init } from '@onflow/fcl-wc'
// example using pairing data from wcRequestHook and providing a custom pairing modal
const { FclWcServicePlugin, client } = await init({
  projectId: PROJECT_ID,
  metadata: PROJECT_METADATA,
  includeBaseWC: false,
  wallets: [],  
  wcRequestHook: (data: WcRequestData) => {
    const peerMetadata = data?.pairing?.peerMetadata
    setSessionRequestData(peerMetadata)
    setShowRequestModal(true)
  },
  pairingModalOverride: (uri: string = '', rejectPairingRequest: () => void) => {
    openCustomPairingModal(uri)
    // call rejectPairingRequest() to manually reject pairing request from client
  }
})

fcl.pluginRegistry.add(FclWcServicePlugin)

@gregsantos should names like includeBaseWC, sessionRequestHook, and pairingModalOveride be more generic so that they can be standards across plugins?
