Contributor guide

Research direction
Read the referenced paper (doi:10.1016/j.jcp.2022.111494) and understand the new flux formulation. Then examine the existing flux implementations in Trixi.jl to see the pattern, and implement the new approximately EC flux for compressible Euler equations. Ensure to write tests and compare with known results.
