Devlog #4 of the Badgeware Tufty Weatherstation

Stuff added in this devlog:

• Indicator to show how many pages there are and which one you’re on
• 16 weather icons that map to the WMO codes that openmeteo gives
• Temperature display (that respects units set in options.json)

Potentially next I’ll code a precipitation levels display, and maybe some charts that show temperature and precipitation throughout the day when you press B.
