[FR] Include usd_value for fee objects in swap json

[smk762]

Describe the bug
Currently swap json includes the fields below:

• Maker side:

				"maker_payment_trade_fee": {
					"coin": "MATIC",
					"amount": "0.086079675",
					"paid_from_trading_vol": false
				},
				"taker_payment_spend_trade_fee": {
					"coin": "KMD",
					"amount": "0.00001",
					"paid_from_trading_vol": true
				},

Taker side:

				"fee_to_send_taker_fee": {
					"coin": "KMD",
					"amount": "0.00001",
					"paid_from_trading_vol": false
				},
				"taker_payment_trade_fee": {
					"coin": "KMD",
					"amount": "0.00001",
					"paid_from_trading_vol": false
				},
				"maker_payment_spend_trade_fee": {
					"coin": "MATIC",
					"amount": "0.03149284582455",
					"paid_from_trading_vol": false
				},

There is also data regarding price of the coins being traded:

	"maker_amount": "0.691555176499475",
	"maker_coin": "CRV-PLG20",
	"maker_coin_usd_price": "0.657",
	"taker_amount": "2.1882427358927014028467925",
	"taker_coin": "KMD",
	"taker_coin_usd_price": "0.2077",

When the fee coin is not the same as the coins being traded (e.g. when trading evm tokens and paying gas in parent coin) there is no data available for the usd price of the fee coin at time of trade.

Including this information would enhance the ability to more accurately determine the total fiat cost of a trade.
