Add forward modelling functions that calculate the magnetic fields of rectangular prisms. One function efficiently computes the three components of the magnetic field, while the other one calculates just one component. The functions make use of Choclo's forward modelling functions, while providing a nice interface, sanity checks and parallelization through Numba. Add examples and tests.

Relevant issues/PRs:

Related to #406

Split the computation of the magnetic fields of prisms in different
functtions: `prism_magnetic_field` returns a tuple with the three components,
`prism_magnetic_easting`, `prism_magnetic_northing` and
`prism_magnetic_upward` return a single component.
Keep only two functions: `prism_magnetic` computes the three components
of the magnetic field, while `prism_magnetic_component` returns only
one, where the choice must be done through the `component` argument.

Based on the idea brought by @aguspesce in one of the Fatiando Community
Calls.
Update the magnetic forward modelling functions so they pass the prisms
boundaries and magnetization vectors to the Choclo functions as scalars.
This change was triggered by the modifications introduced in
fatiando/choclo#50

Looks great! I'll fix a small typo, and ready to go 😄
