Function: horizonAltAt()
function horizonAltAt(profile, azDeg): number;
Skyline altitude at an azimuth from an observer obstruction profile: piecewise-linear interpolation on the circle. The profile need not be sorted; azimuths are normalized to [0, 360) and the interpolation wraps across 360/0. An empty profile is the astronomical horizon (0 deg).
