* Refactored `remindme_caldav.py` to separate concerns into different functions:
- `calendar_parser()`: Parses the calendar and generates event dictionaries.
- `generate_recurring_event_dates()`: Generates recurring event dates based on a start date and an RRULE.
- `get_next_alert()`: Calculates the next alert time for each event.
- `process_alert()`: Processes alerts for each event.
* Implemented error handling in `calendar_parser()` to catch missing components without crashing the program.
* Added comments and docstrings for better code readability and maintainability.
* Modified `get_next_alert()` to handle events with no recurring dates.
* Updated `process_alert()` to subtract 15 seconds from the next alert time to ensure alerts are triggered before the event occurs.
* Added a human-readable format for the time until the next alert in the status message.
* Update import statement in email_alert.py to include humanfriendly library
* Modify send_email function signature in email_alert.py to accept an event dictionary instead of separate arguments
* Extract event name, description, location, date, and time until event from the event dictionary and use them in the email body
* Update email body format string accordingly
* Use humanfriendly library to format time difference between next alert and next event into a human-readable format.
