Connector gitlab/ics calendar/paperless

I have written a small connector that synchronizes data from ICS calendars, multiple GitLab instances, and Paperless instances into my Logseq. As a result, I have much more information available at a glance and can find my information faster.
I hope that others can also find some use for this.

I haven’t been working with GO for a very long time, so any suggestions for improvements through a Pull Request (PR) are welcome. :wink:
