Much better responses from the various functions

[TwitchBronBron]

Sometimes roku-deploy just returns a string as the response from doing something. That's not overly helpful .We should do a much better job return a structured response/status object so the callers can make more informed decisions about this stuff.

Problems to solve:

• roku has info, warn, error stuff. we're not logging those. we should. So if we're gonna throw, we should log better reasons why.
• our tools like vscode are likely not taking advantage of this when it could. we're just looking at "it threw" and logging it. We should try passing along info, warn, error stuff to the console.

We might need to append rokuMessages to every error.

interface RokuDeployError {
    message: string;
    stack: any;
    rokuMessages: RokuMessages;
}
