Increases planetary diameter precision

Removes final rounding from computed apparent diameters so values are no longer quantized to 0.1, improving accuracy of graphs and visualizations for affected planets (Jupiter, Mercury, Venus, Mars, Neptune, Uranus, Saturn).

Updates changelog to record the new version.
