Much improved; yeah, let's only use the precompiled data solution when we have astonomy going on. The formulas implementing islamic-tbla and islamic-civil are very straightforward.

Thought: I wonder if we could make islamic-umalqura and islamic fall back to one of the formulaic calendars for distant dates instead of carrying around the astronomy code at runtime.
