This PR fixes chart display with the quaternion version of the integrator.
Fixed by rotating the chart by
-parallactic_anglerather thanroll.When
mount_typeis alt/az, it will correctly display the chart in horizontal coordinates. If themount_typeis equatorial, it will display the chart in equatorial coordinates (north-up in norther hemisphere and south-up in southern hemisphere). If location or time is not available from the GPS, the chart display will default to equatorial coordinates (north-up).Sky tested (f53401a) 1 May 2026 in the northern hemisphere.
