Wrong boys2rgb colormap

[zhenchen-jay]

Description

I think there is a typo in the function boys2rgb

https://github.com/fury-gl/fury/blob/master/fury/colormap.py#L118

it is actually should be:
z4 = z2 * z2

This can be also seen in the initial matlab code: https://cagataydemiralp.io/projects/boys/line2rgb.m

Way to reproduce

• Code example

import numpy as np
from fury import colormap

if __name__ == '__main__':
    v = np.array([[0.0183422, 0.00418003, 0.999823], [-0.0183422, -0.00418003, -0.999823]])
    print(colormap.boys2rgb(v))

• Result

[[0.49262681 0.48131988 0.05134322]
 [0.49262681 0.48131988 0.87099833]]
