RoR Auto Ambience

You can select from four "ambience" settings for Deek to apply to the Room of Requirement ("RoR"). Two of them look like day-time and two look like night-time. Once you've chosen an "ambience" it remains fixed until the next time you change it. This can be a little jarring if you go from blazing noon-time sun outside to dark night-time inside. This mod will keep the ambience inside the ROR aligned with the time-of-day outside the RoR by cycling through the four ambience settings, changing from one to the next every six in-game hours at approximately (within 15 real-world seconds of) the following in-game times:

1. Night-time1 = 5pm (it gets dark at about 5pm in the winter in Scotland)
2. Night-time2 = 11pm
3. Day-time1 = 5am
4. Day-time2 = 11am
