* Added UI infastructure to support chain switching, need to update the session to swap chains
* Fixed type of chainId, string -> number
* Added helper method to find full chainname ex/ cosmoshub-4 -> cosmons:cosmoshub-4. Added a method updateSignClientChainId to emit a new update with the new namespace for the respected chain switch
* Added checks to ensure no dup accounts get added to namespaces during chainswitching from chain A->B->A for ex
* Fixed chainId type, eip155 uses number but the other chains use strings, making string the default type for chainId
* Update wallets/react-wallet-v2/src/utils/WalletConnectUtil.ts
