Options to Disable or filter for ASCII Art

**Is your feature request related to a problem? Please describe.**
I'm somewhat frustrated when the ASCII art is filling up the syslog every hour (more so when logcheck then emails it to me) [...]

**Describe the solution you'd like**
I'd like an option to disable the ascii art, even if its a local config only.

**Describe alternatives you've considered**
I am (trying) to write a regex to exclude it but i'm not super good at regex.

**Additional context**
I think its very cool and I like it, until it started sending emails, every hour. I understand it needs to log, but maybe contribute an ascii art filter to [https://salsa.debian.org/debian/logcheck], [https://launchpad.net/logcheck] or [https://launchpad.net/ubuntu/+source/logcheck]

まず、拡張機能が1時間ごとのASCII artを出力する場所と、ローカル設定オプションがどのように処理されているかを特定します。loggingの動作に既存のテストがあるか確認します。ユーザーが文書化されたローカルオプションによってASCII artを無効化またはフィルタリングでき、他の拡張機能のloggingに影響を与えなければ完了です。
