Draft: Correcting electromagnetic field particle advection for WarpX
The earlier implementation did not accurately advect particles in electromagnetic fields. This merge request fixes the Lorentz force calculation needed to evaluate the charged particle velocities correctly. The calculation is based on the Boris pusher (see: https://warpx.readthedocs.io/en/latest/theory/picsar_theory.html)
