v0.1.6

Features

• leader_offset(tip, direction, length, label, draft) (#6): place a leader's elbow by compass direction ("N", "NE", …, case-insensitive) or numeric angle (degrees CCW from +X) and a distance, instead of absolute page coords. Thin wrapper over leader() — useful when the drawing uses a non-1:1 scale and elbow arithmetic gets noisy.
