Improved API parsing logs

Rather than having all error log messages verbosely use the same format
<response name> missing key \"<key name>\", maybe the extra argument could be responseName: String instead of errorLogMessage: String, and build the error message with that?

Even better, just add an extra convenience method

    static func parse<T>(key: String, from data: [String: Any], responseName: String) throws -> T {
        try Self.parse(key: key, from: data, errorLogMessage: "\(responseName) missing key \"\(key)\"")
    }

So we could easily differentiate the message if need be in the future?

I didn't really know what message I'd use initially so I just added a String and ended up using the same message everywhere :). Anyway I changed it to pass Class.Type so that you get autocomplete and avoid typos. If we want different message somewhere sometime in future we can overload the function. See 929316d
