RangeError: Maximum call stack size exceeded with customize formatter

See below codes

var winston = require('winston');
var request = require('request');
var util = require('util');

var logger = new (winston.Logger)({
  transports: [new winston.transports.Console({
    level: 'info',
    exitOnError: false,
    json: false,
    formatter: function defaultFormatter(options) {
      console.log('formatter is called');
      return options.message + '\n' + util.inspect( options.meta, {depth: 1});
    }
  })]
});

request.get('http://www.google.com', function(err, resp){
  logger.info('Log response object.', resp);
});

When execute above code, RangeError occurs. And formatter is called is not printed in log

Similar to #100

The fix is add below code before https://github.com/winstonjs/winston/blob/master/lib/winston/common.js#L217

options.meta = meta;

Need to have options.meta decycled before clone.
