BREAKING CHANGE: AeppRpc doesn't accept `connection` anymore
Use `connectToWallet` method instead.

BREAKING CHANGE: `handlers` parameter is removed in RpcClient
Provide a `methods` parameter instead of `handlers[0]`.
Provide an `onDisconnect` parameter instead of `handlers[1]`.

BREAKING CHANGE: `sendMessage` of RpcClient is a private method
Use `request` or `notify` instead.

BREAKING CHANGE: `shareWalletInfo` of WalletRpc accepts rpcClientId instead of callback
For example, rewrite
```
const connection = new BrowserRuntimeConnection({ port })
aeSdk.addRpcClient(connection)
aeSdk.shareWalletInfo(port.postMessage.bind(port))
```
to
```
const connection = new BrowserRuntimeConnection({ port })
const rpcClientId = aeSdk.addRpcClient(connection)
aeSdk.shareWalletInfo(rpcClientId)
```

BREAKING CHANGE: `connectToWallet` accepts wallet connection as the first argument
See connect-aepp-to-wallet.md for details.

BREAKING CHANGE: `disconnectWallet` runs in sync and `sendDisconnect` arg removed
So, aepp would always send `closeConnection` notification.

BREAKING CHANGE: `sendConnectRequest` removed
Use `connectToWallet` instead.
