linearize and make_dual_shadow accept a BodyAerodynamics with more... #344
Description
linearize and make_dual_shadow accept a BodyAerodynamics with more than one wing
Split out of #330 (stability derivatives and trim search on linearize), which needs it to cover multi-wing bodies.
linearize (src/solver.jl, the length(body_aero.wings) == 1 guard) and make_dual_shadow (its own one-wing guard) reject a body with two wings. The va and omega columns need nothing per wing; theta_idxs/delta_idxs are one entry per unrefined section of the one wing, so for several wings they would run over the unrefined sections of all wings in order, matching moment_unrefined_dist, which the solver already sizes by the sum over wings.
Test: the two-wing bodies in test/body_aerodynamics/test_body_aerodynamics.jl (solve! on a two-wing body), Jacobian against AutoFiniteDiff as test/solver/test_forwarddiff.jl does for one wing.

Merged main (#352), CHANGELOG only. Now addressing the review on #355: a test that the twist and deflection split hands each wing its own angles, tighter bounds on the far-apart test, and one helper for each wing's unrefined-section range, used by calc_forces! and unrefined_deform!. Opening issues for ELLIPTIC on several wings and for wings[1].spanwise_direction.
