Potential need for update to accommodate for crypto

[MuneMalik]

I've been hacking away using the package in an application I'm creating, and the api requests for stocks seems to be working fine. The issue I'm having is with crypto. I know that the requests accommodate for crypto, but I don't think the responses do. Unless, I'm doing something completely wrong.

I've attached some code here to show you what I'm trying along with a screenshot of the error popping up.

    polygon.tickers(sort: .ticker, order: nil, type: nil, market: .Crypto, locale: nil, ticker: "X:ETHUSD", limit: 50, active: true) { (result:TickersQueryResponse?, err) in
        // check if we got any errors
        if let err = err {
            print(err)
        } else {
            print(result)
            print(result?.results)
        }
    }

I'd love to help out with this if thats something I can do. If I'm on the right track with the issue, then I could go ahead and get started on working on it. I just wanted to know if the direction I'm going in is correct!
