Add MVAE algorithm following Sonnerup & Scheible (1998). For a 1D current layer, the normal direction has maximum electric field variance (unlike MVAB where the normal has minimum magnetic field variance). New public API: - mvae_eigen(E): eigendecomposition with max eigenvalue = normal direction - mvae(V, E): transform timeseries to MVAE coordinate system - check_mvae_eigen(F): quality check using λ₁/λ₂ ratio - convection_efield(v, B): compute E = -v×B proxy electric field Also adds E_x1_error for MVAE error estimation, DimensionalData extension support, and comprehensive tests. https://claude.ai/code/session_01NJD1MCzbYteJBHoFu6K3vC
