docs: Creates a LogTee that writes to a file "filename" and another stream (stdout by default).
  
  @param filename the name of the log file (if relative, it will be resolved from process.cwd())
  @param stream2 the second stream to send output to
  (defaults to process.stdout, provide "null" to send output only to the file)
