Implement Bloch Sphere rendering

[albertomercurio]

Problem Description

Implement the Bloch Sphere rendering. It should follow the same syntax as QuTiP, as showed in this page.

It should also follow the methods already defined for the plot_wigner and plot_fock_distribution functions, allowing for future possible alternative backends. Makie should be enough for the moment.

Proposed Solution

The Bloch sphere constructor should be defined like

b = QuantumToolbox.Bloch()

All the attributes have to be defined using functions like

pnt = [1/sqrt(3), 1/sqrt(3), 1/sqrt(3)]
add_points!(pnt) # Notice the exclamation mark, as it changes the structure of the object
render(b)
