New scripts/generate_castellated_edge.py produces a reusable footprint
(round PTH pads + an embedded Edge.Cuts line through their centers) for
mounting a module flush onto another board's edge, ESP32-WROOM style --
distinct from the QFP/SSOP breakout-adapter footprints already in
footprints/other/castellated_breakouts.pretty/. Default pad size (1.0mm
dia / 0.5mm drill) matches the vias used in reference/kicad-castellated-breakouts.
Generated CASTELLATED_EDGE_1x20_P1.27MM (20 pins, 1.27mm pitch) into
footprints/other/castellated_edge.pretty/, registered as
MIKILAB_castellated_edge.
