Kucoin perpetuals - history displays incorrect fees paid

[rapcmia]

Describe the bug
While checking kucoin_perpetual trade data we notice that the fees paid does not match between client and kucoin's exchange trade history. Based on kucoin future trading fees default 0.02%/0.06% (maker/taker) which is correct on kucoin_perpetual_utils.py however this is not the case for the client when tested on different markets {XRP-USDT, LINK-USDT} For calculating the fees we assume this calculation (price * order_amount) * fees rate

Sample scenario on the attached CSV
The price is 0.419 with order_amount of 20XRP and fee is 0.02% on trade history in which we expect should be around 0.001676 however on the CSV file its returning value is 0.20

{'fee_type': 'DeductedFromReturns', 'percent': '0', 'percent_token': 'USDT', 'flat_fees': [{'token': 'USDT', 'amount': '0.20'}]}

Steps To Reproduce

1. Setup simple perpetual market making strategy
2. Setup spreads enough for trade
3. Check history, CSV and kucoin trade history
