Descrizione

As suggested by @gregorgassner in https://github.com/trixi-framework/Trixi.jl/pull/274#discussion_r515895414.

Something like weights2d, weights3d could be added to the cache of the semidiscretization.

Direzione di ricerca
Start by reviewing the linked PR #274 discussion, especially the comment by @gregorgassner. Examine the current implementation of `weights2d` and `weights3d` in the source code to understand how they are computed. Then, explore the semidiscretization cache structure to identify where to add these precomputed weights. The goal is to benchmark the performance improvement of caching these weights versus computing them on the fly. Consider writing a small script to test both approaches.
