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]

Start by locating where the extension emits the hourly ASCII art and how local configuration options are handled. Check whether the logging behavior has existing tests. Done means users can disable or filter the ASCII art through a documented local option without affecting other extension logging.
