Extend basic LinearAlgebra methods; update manifest and Julia
- Manifest updated to version 2.0 and Julia to version v1.10.
- Fix LinearAlgebra.norm extension.
- Extend several other LinearAlgebra basic methods.
- Add non-trivial test of these functions by computing
det(M) * det(inv(M))of a 2x2 matrixM, which should be 1. The inversion ofMis computed using the conjugate gradient algorithm.
