feat(walletconnect): add wallet connect support to UnityEditor (#143)

Add a new `WalletConnectAccount` and `WalletConnectAccountAsset` to manage WalletConnect accounts in the editor.

BREAKING CHANGE: `AlgorandWalletConnectSession` flow has been changed to reflect new `JsonRpcClient`. 
- `StartConnection` renamed to `Connect`
- `Disconnect` renamed to `DisconnectWallet`
- `WaitForConnectionApproval` renamed to `WaitForWalletApproval`
- `SavedSession` renamed to `SessionData`
