Subscribe to XBT currency pairs are not supported

[Strebor]

Describe the bug
After recent updates, it's no longer possible to subscribe to trade updates for any XBT currency pair, e.g., XBTUSDT, XBTUSDC, XXBTZEUR, etc.

To Reproduce
IKrakenSocketClientSpotApi SubscribeToTradeUpdatesAsync result.Error.Message is "Currency pair not supported XBT/USDC"

Expected behavior
Subscription success, like for any other currency pair in the Kraken Coin list.

Hi, the library has been updated to Kraken websocket version 2.0. This version uses BTC instead of XBT for asset and symbol names, and removes additional chars for fiat assets.
So for example:
XBT/ETH => BTC/ETH
ZEUR/ZUSD => EUR/USD

To programatically retrieve the new names you can use this call (note the newAssetNameResponse parameter):
var symbols = await krakenRestClient.SpotApi.ExchangeData.GetSymbolsAsync(newAssetNameResponse: true);

[Strebor]

Great, thanks. This makes all the difference, and finally the symbols match the other Kraken platforms.

If I may ask a related question here. KrakentRestClient.SpotApi.Account.GetBalancesAsync() returns crypto symbols using the 'old' asset names. Example:

ADA
TRX
XLTC
XXLM
XXRP
ZEUR

Is there a switch for this one too?
Otherwise, it's not really that hard to remove the prefix for names that don't match those returned by GetSymbolsAsync(newAssetNameResponse: true)

[JKorf]

The newAssetNameResponse parameters are not documented, so it's a bit hard to check where it's supported and where it isn't. I've tried a few endpoints, and not all seem to support it, but the GetBalancesAsync call does. So I added the parameter there in the latest version!

I've found another spot for you. SpotApi.Trading.GetOpenOrdersAsync() returns KrakenOrderInfo like this:

...OrderDetails = KrakenOrderInfo { Symbol = TRXEUR, Side = Buy,...

[Strebor]

fyi, the KrakenSymbol WebsocketName seems correct for all symbols except for BTC pairs. It's coming in as XBT which fails when subscribing.
