How do you feel about making a backup alg which is LinSolver, and just returning fpgrad(args..., alg::LinSolver)? It removes a tiny bit of code, but it might also be slightly more readable.

Changes the default fixed-point gradient algorithm to
:eigsolver, and adds a fallback linsolve in case the eigsolver approach fails.
