feat: cron jobs / automation on Python or SQL scripts

[waveminded]

Users have expressed the ability to run Python scripts on a frequency to potentially update a Quadratic sheet automatically.

For example: a data analyst creates a script that generates a data report in Quadratic. This report is shared with fellow team members. The analyst has to re-run the script manually to create a fresh report and then let their colleague know the report has been updated. By automating this workflow an analyst could create a reporting tool that automatically refreshes and updates the associate team members.

It’s easy to implement a client, side, refresh interval, that replaces existing data. I think we’d want to start with that. Then add server-side interval, were you also have the option to append new data, instead of overriding it. This would run in the background, regardless of the file was open by the client or not
