Previously the array sim only excited a single inner element (DRIVEN_X / DRIVEN_Y). Adds DRIVEN_PORTS env var accepting a comma/semicolon-separated list of "i,j" pairs that are all excited in-phase with equal amplitude — models a perfect 1:N corporate splitter feeding an N-patch sub-array. Example: DRIVEN_PORTS="0,0;1,0;2,0;3,0;0,1;1,1;2,1;3,1" excites a 4-cols × 2-rows sub-array anchored in the corner. S-parameter post-processing reframed for the multi-driven case: each excited port reports active-S11 (uf_ref/uf_inc with all driven ports active); each non-excited port reports S relative to a representative driven port's incident wave (all driven ports have equal amplitude so any reference works). Backwards-compatible: empty DRIVEN_PORTS reverts to single-port DRIVEN_X / DRIVEN_Y behaviour.
