This PR introduces a new single-step paired explicit Runge-Kutta integrator of the third order. Along with this implementation, NLsolve has been added as a weak dependency.
Tests have been added for the example elixir_burgers_perk3.jl both with and without the fixed time step. Additionally,
methods_PERK2.jlis also modified so that some functions can also be called by the third-order integrator.Please feel free to let me know if there is anything that is missing or needs improvement!
