ob_start error in html output

[JohnAdib]

I have this errors in windows

Warning: ob_start(): output handler 'ob_gzhandler' conflicts with 'zlib output compression' in D:\xampp\htdocs\Projects\github\linfo\src\Linfo\Output\Html.php on line 150

Notice: ob_start(): failed to create buffer in D:\xampp\htdocs\Projects\github\linfo\src\Linfo\Output\Html.php on line 150

probably it's because don't clean last ob_start and start again. it try to fix this and send as pull request
