Description

This PR fixes issue #125 by updating the layer matching logic in the KiCad mod parser to properly handle the ‘*.Cu’ layer pattern.

Problem

The original code only checked for exact matches of ‘F.Cu’ when determining if a pad should be processed. This caused pads with ‘*.Cu’ layers to be skipped, leading to:

• Pads being processed as holes instead of pads
• Missing pin labels in the output
• Incorrect component dimensions

Solution

• Updated the layer checking logic to recognize ‘*.Cu’ as a valid Cu layer pattern
• Added logic to prevent duplicate processing of pads in the holes section
• Maintains backward compatibility with existing ‘F.Cu’, ‘B.Cu’, and other layer patterns

Testing

• ✅ Tested with the problematic ADOM_MEDIUM_PIN_SHORTER_v1.kicad_mod file
• ✅ Verified no duplicate processing occurs
• ✅ Confirmed pin labels are properly handled
• ✅ Ensured backward compatibility with existing test files
• ✅ No undefined values in output

Changes

• Modified src/parse-kicad-mod-to-kicad-json.ts to improve layer matching logic
• Added duplicate prevention logic in holes processing section
