Plane Transformation

[arpastrana]

Describe the bug
When attempting to transform a Plane in place via its transform() method, error is raised in line 248 of compas.geometry._primitives.plane.py when trying to coerce the first entry into a float as it it thinks the output of compas.geometry.transformations.transform_points() is a single list . However, the returned value of the latter function is a in fact a nested list.

To Reproduce

from compas.geometry import Plane
from compas.geometry import Point
from compas.geometry import Vector
from compas.geometry import Rotation

plane = Plane(Point(0, 0, 0), Vector(0, 0, 1))
rot = Rotation.from_quaternion([0, 1, 0, 0])
plane.transform(rot)

Expected behavior
Transformation successfully applied to Plane.

Closed with #261. Awaiting for merging stuff in the branch feature/geometry_primitives_update, which is soon to merge, in order to address this and a range of other inconsistencies.
