support open session early setting when marking with automatic attendance

[AlbertoAdvWork]

Hello
The plugin has great features but it has a basic problem: if you set the automatic attendance recording feature, it only considers accesses exclusively within the session, discarding the value set in "Open session early for marking".
Example: I have a session from 9.00 to 13.00, but it is rare that people enter after 9.00. It would be useful if attendance recording started from 9.00 minus the minutes indicated in "Open session early for marking": if I set 25 minutes, it should consider all accesses to the course starting from 8.35.
Or at least have the option to do so!

Thanks for the report - when implementing the open session early setting I hadn't considered people would want to use it with the automatic attendance recording feature but it makes sense that people would want to use this. I don't know if I'll get a chance to work on this improvement as a volunteer, but if you have internal development capabilities feel free to submit a pull request with this improvement, or reach out privately if you would like to fund the time required to make these changes.

thanks!
