Pull request overview

This PR introduces a Next.js application that uses OCR technology (via Google's Gemini AI) to extract timetable information from images and convert it to iCal format for calendar import. The implementation targets Singapore school timetables with odd/even week scheduling patterns.

Key changes:

• Integration with Google Gemini AI API for OCR processing of timetable images
• Calendar generation functionality that converts extracted data to iCal format with recurring events
• React-based UI with file upload, data editing, and export capabilities

Using "any" type for rrule defeats TypeScript's type safety. Consider defining a proper type for the recurrence rule object or importing the appropriate type from the ical-generator library if available.

The dependency "@types/pdf-parse" is not needed since "pdf-parse" itself is unused and should be removed along with the main package.
