Checkstyle severity level is incorrect #67
Description
in the CheckStyleOutput class, the severity is set to ERROR:
PHP-Parallel-Lint/src/Output.php
Line 442 in 02a09f1
Following the Checkstyle specification, allowed values are:
ignore, info, warning, error, all lowercase.
When using cs2pr to annotate files in github, this results in the annotations showing as warning (default) instead.
I think it would actually make sense to use warning for deprecation notices.
