This patch improves upon @shrapnel 's work on the accuracy of the Taiwanese holidays file:
- Some holidays are determined based on the Lunar Calendar, and their specific dates have to be manually specified for each year
- Official holiday names are now used
- Try to put a holiday in the correct categories
The following has been excluded:
- Holidays (Festivals) for indigenous peoples (原住民族歲時祭儀)
- Non-official holidays such as Halloween and Christmas
