wss://iex-business.polygon.io is missing from the feeds constants.

Describe the bug

There is a websocket feed missing from the constants. For websocket subscriptions to Trades I am required to use the wss://iex-business.polygon.io domain but this is not an option. I am able to override this, but for completeness and because one cannot subscribe to IEX trades or quotes without it, it should be included as a constant with the rest of the feeds here:

client-go/websocket/config.go

Lines 59 to 77 in fb8e9d4

	const (
	Delayed Feed = "wss://delayed.polygon.io"
	RealTime Feed = "wss://socket.polygon.io"
	Nasdaq Feed = "wss://nasdaqfeed.polygon.io"
	PolyFeed Feed = "wss://polyfeed.polygon.io"
	PolyFeedPlus Feed = "wss://polyfeedplus.polygon.io"
	StarterFeed Feed = "wss://starterfeed.polygon.io"
	LaunchpadFeed Feed = "wss://launchpad.polygon.io"
	BusinessFeed Feed = "wss://business.polygon.io"
	EdgxBusinessFeed Feed = "wss://edgx-business.polygon.io"
	DelayedBusinessFeed Feed = "wss://delayed-business.polygon.io"
	DelayedEdgxBusinessFeed Feed = "wss://delayed-edgx-business.polygon.io"
	DelayedNasdaqLastSaleBusinessFeed Feed = "wss://delayed-nasdaq-last-sale-business.polygon.io"
	DelayedNasdaqBasicFeed Feed = "wss://delayed-nasdaq-basic-business.polygon.io"
	DelayedFullMarketBusinessFeed Feed = "wss://delayed-fullmarket-business.polygon.io"
	FullMarketBusinessFeed Feed = "wss://fullmarket-business.polygon.io"
	NasdaqLastSaleBusinessFeed Feed = "wss://nasdaq-last-sale-business.polygon.io"
	NasdaqBasicBusinessFeed Feed = "wss://nasdaq-basic-business.polygon.io"
	)

To Reproduce

It's a missing constant so I guess try and create a new websocket connection with BusinessFeed and try to subscribe to a Trade. It will not work

c, err := polygonws.New(polygonws.Config{
	APIKey: polygonApiKey,
	Feed:   polygonws.BusinessFeed,
	Market: polygonws.Stocks,
	Log:    logger,
})
// This will not work
if err := c.Subscribe(polygonws.StocksTrades, "TSLA", "GME"); err != nil {
    log.Fatal(err)
}

Expected behavior

This used to work. It no longer does as IEX data has to be subscribed to from wss://iex-business.polygon.io

Screenshots

Additional context

Not sure if this is a bug or an enhancement but since previous functionality no longer works without a change, I figured it was a bug.

Thanks. We have a PR here #511. I'll get it merged and cut a release asap. Sorry about this.

Hey @sarcastron, the PR has been merged and v1.16.10 has it. You should be able to use Feed: polygonws.IEXBusiness for accessing the IEX data now.

@justinpolygon Thank you so much!

No worries. Thanks for reporting that @sarcastron!
