khcchiu 8617b50ff6 Exchanges: enrich order history with avg executed price, cost, and more (#792)
* Exchanges: enrich order history with avg executed price, cost, and more

* Fix division by zero in order detail enrichment

* Remove DateCompleted from Bithumb OrderData and fix OrderDate parsing

* Fixes on order detail fields and rename EnrichOrderDetail to CalculateCostsAndAmounts

* BTSE order history populate name and id

* Calculate average executed price for market order or when order amount is zero

* Minor fixes on infer order amounts, costs, and times

* Attach InferAmountsCostsAndTimes to Order.Detail

* Binance: fix order status

* Always use order.StringToOrderStatus() and ensure order has at least one of executed/remaining amount set
