Customize colors per log level

[yoav85]

Maybe it's possible with custom formatting, but not sure how to achieve that. For example, I'd like to change the colors that render for each log level in the debug console, perhaps even apply that color to the whole line (not just the word which indicates the log level). Thanks

ideally the FormatMessage function the log level in its signature. something like this would allow setting color for the message to match the level.:

func(i interface{}, level zerolog.Level) string {
....
}
