tdf#104428 Improve rendering of exploded donut charts

This bug shows an exploded donut chart with more than one series. The
concern is that the standard pie/donut' explosion' rendering, with the shape
of the pieces unchanged but the pieces translated outward, gives
unsatisfactory results in the case of a donut with more than one series,
where the translated 'exploded' pieces can overlap with the inner ring.
This proposed fix renders this case differently, by increasing the radius
of the exploded ring but keeping the pieces concentric with the inner ring.

This commit also modifies the unit test values for donut_chart.ods.
