  CEF spaces between each character
  I followed the 7 steps https://cowrie.readthedocs.io/en/latest/INSTALL.html#step-1-install-dependencies
  
  I set up cef in the config file 
  `
  [output_localsyslog]
  enabled = true
  facility = USER
  format = cef`
  
  But the output I'm getting has a bunch of spaces it seems to have a space between each character below
