Improved Stats (Years Views + Streak Calendar)

This update reorganises how statistics are displayed:

• The view is split up into years and you can now flick through them.
• Each year has a calendar streak heatmap to show consistency along with all the normal graphs from before!
• Dates have been readded onto the graph popup

To update the extension please:

1. Backup your lines and statistics
2. Drag and drop the extension into your browsers extension page
3. Make sure your lines and stats are all good
4. Enjoy :)
