colorized logs

It would be nice to add support for color. This can be done by parsing the message and using the winston.config.colorize method.

@mikestaub I don't use colors in Papertrail, so I'm not sure what is necessary to do this. Do you think that adding console: { colorize: true }, to these options:

serverless-papertrail-logging/src/logger.handler.js

Line 40 in 864d632

logger.add(papertrail, {

(according to https://github.com/winstonjs/winston#working-with-multiple-loggers-in-winston) is enough?
