CryptoClients: Kucoin Balance Updates in cross margin mode

[PhilAlain]

Hello again Jan,

We are testing Balance updates for Kucoin.

Our use-case is the following: cross margin mode

As per Kucoin API documentation, when in cross margin mode:
the following subjects of this topic will stop pushing
"subject": "orderMargin.change",
"subject": "availableBalance.change",
"subject": "withdrawHold.change",
Use the following subject to replace
"subject": "walletBalance.change"

https://www.kucoin.com/docs-new/3470092w0?x=fr_FR&

CryptoClients does receive the update, but does not wire it back as a result (cf. trace below)

Probably something around KucoinSocketClientFuturesApi

            var result = await SubscribeToBalanceUpdatesAsync(
                onBalanceUpdate: update => handler(update.ToType<SharedBalance[]>(new[] { new SharedBalance(update.Data.Asset, update.Data.AvailableBalance, update.Data.AvailableBalance + update.Data.HoldBalance) })),
                ct: ct).ConfigureAwait(false);

Need to handle onWalletUpdate also.

Hi, I've added the onWalletUpdate handling so it should work correctly now
