Adjust time approximations

[Hirmuolio]

Summary

Interface "Adjust time approximations"

Purpose of change

The approximate time did not match with apparent time of day. Sunset and sunrise especially can move by several hours depending on time of year.

This led to confusing situations like it being "dead of night" at 04:20 while the sun is already up and it is fully bright.

It also seems like the original writer forgot about integer rounding on some of the times and they last one hour too late.

Fix: #58010

Describe the solution

Use mixture of clock times and sun angles to decide what time it is.

The new definitions can overlap sometimes. The one listed first in the table will be used.

Time	Old	New
Around midnight	23:00-01:59	23:00-01:00
Around dawn	06:00-06:59	Sun between -6° and -1° (in morning)
Around dusk	19:00-20:59	Sun between -6° and -1° (in evening)
Dead of night	02:00-05:59	01:01-03:59 and sun below -6°
Night	20:59-23:00	Sun is below -6°
Early morning	07:00-08:59	01:00-07:59
Morning	08:00-10:59	08:00-10:59
Around noon	11:00-13:59	11:00-12:59
Afternoon	13:00-16:59	13:00-16:59
Early evening	17:00-18:59	17:00-18:59
Evening	-	19:00-20:59
Night	21:00-22:59, 06:00-06:59 (when nothing else matches)	when nothing else matches

Earliest sunrise/latest sunset that currently can happen ingame is at around 04:00/19:30.
Latest sunrise/earliest sunset that currently can happen ingame is at around 07:00/16:00.
I think these will work decently fine for the current game location (Boston). Once modding or travel allows changing the game latitude we will need some handling for midnight sun and polar night. But those can't happen currently.

Also adjusted is_night() to define night to be below -6° instead of -12° and is_twilight() (and by proxy the is_dawn() and is_dusk() too) to be from -6° to -1° instead of -18 to -1°`.

Describe alternatives you've considered

The survivor does not care about social construct like "time of day". If they have no clock the time approximation could be just directly based on sun angle/light levels and ignore the actual time completely.

Survival skill could also make time approximations more accurate.

Testing

Changed time with debug menu and observed the correct time descriptions.
