Missing POJOs for `PostOrderRequest` OCO order `setStopLoss` and `setTakeProfit`

[Petersoj]

Alpaca's OpenAPI spec sets stop_loss and take_profit to a type of "object", which doesn't generate the POJOs for OCO orders. Refer to this Slack thread for the initial discussion of this issue.

Hi @Petersoj !
This request is exactly what I need to finish my development. Do you think you could also solve this issue at the same time you will update the OpenAPI generated objects ?

Many many thanks.

Actually, I looked at the current OpenAPI json version of Trader, and stop_loss and take_profit are still objects....
So cannot be generated directly.
As a consequence, we have to pass a map to the Stop_Loss object, for example in Kotlin:

val stopLossMap = mapOf("stop_price" to "200.0", "limit_price" to "200.0")
        alpacaAPI.trader().orders().postOrder(
            PostOrderRequest().symbol(assetName)
                .qty(quantity.toString())
                .type(OrderType.MARKET)
                .timeInForce(TimeInForce.DAY)
                .side(OrderSide.BUY)
                .orderClass(OrderClass.OTO)
                .stopLoss(stopLossMap)
        )
