zreversed feature in Axis3

[Undermine28]

In aerospace, many coordinate systems are defined with a positive Z direction down. Currently, Axis3 does not support flipping the default direction of any of the axis. For example the vehicle-carried normal Earth reference frame:

Feature description

A parameter similar to axis xreverse = true and yreverse = true but for axis3.

The critical difference here is that the coordinate system should ideally remain right-handed. Another feature could be to change from right-handed to left-handed. But the default behavior should keep right-handedness for consistency.

Plot examples of what the final feature should do.

First, we have what is currently the default:

Next, we have the plot with the z+ direction downwards. Notice the y-axis stays in the negative region but also changes direction to maintain right-handedness.

(I made the graphs for illustrative purposes by rotating the data around the x-axis and then editing out and in the - tick markers where appropriate)
