benchmarks for sparse decompositions

[martinjrobins]

Thanks for all the work on this excellent crate. I'm using faer's sparse LU decomposition in an ode solver and trying to interpret some of my own benchmarks. I'd like to quantify the impact of faer's LU decomposition, so I was wondering if there was any benchmarks available for this, similar to the dense benchmarks you have already published?

Specificly I'm interested in benchmarks for faer's LU sparse solver against the KLU sparse solver in suitesparse, but any benchmarks would be appreciated. Thanks!
