How to use other log modules than Logger4

import {Logger4V2} from 'logger4'

const x = new XAPI({...loginConfig, logger: new Logger4V2()})

const info = new Writable()
info._write = ((chunk, encoding, next) => {
  // you can bind 'info' logger
  console.log(chunk.toString())
  next()
})
x.logger.onStream('info', info)

const error = new Writable()
error._write = ((chunk, encoding, next) => {
  // you can bind 'error' logger
  console.error(chunk.toString())
  next()
})
x.logger.onStream('error', error)

const debug = new Writable()
debug._write = ((chunk, encoding, next) => {
  // you can bind 'debug' logger
  console.log(chunk.toString())
  next()
})
x.logger.onStream('debug', debug)
