Add shape and workplane support to the Workplane.eachpoint() function. Issue #1395

[dov]

This PR solves issue #1395 and adds the ability to use the Workplane.eachpoint() function with a Shape and a Workplane.

Here are is an example for using a wire to do a cutThru():

wire = Wire.makeCircle(1, (0, 0, 0), (0, 0, 1))
result = (
    Workplane("XY")
    .box(10, 10, 1)
    .faces(">Z")
    .rect(7, 7, forConstruction=True)
    .vertices()
    .eachpoint(wire)
    .cutThruAll()
)

And here is an example for using another workplane, adding a sphere to the center of each face:

box = Workplane().box(2, 2, 2)
sph = Workplane().sphere(1.0)
# Place the sphere in the center of each box face
r = box.faces().eachpoint(sph, combine=True)

@dov could you run black?

@adam-urbanczyk Ok. I just did. It isn't trivial since the rest of the files are not compliant.

(However, I just found "darken", which makes it easy).
