Pull Request Overview

This PR introduces a relativistic Boris pusher to support simulations involving relativistic plasmas and updates the simulation, particle, plotting, and configuration files accordingly.

• Added a new parameter "relativistic" in simulation initialization and input configurations.
• Integrated a new relativistic Boris pusher branch that leverages a new function boris_step_relativistic.
• Adjusted plotting parameters and configuration values to align with the relativistic update approach.
