Integrate CAPEC patterns into D3FEND

[aamedina]

Addresses #257

This PR integrates CAPEC named individuals into the ontology. A new Python script parses CAPEC XML files, generates OWL classes, and maps related CWEs and ATT&CK techniques.

• Added a script to parse CAPEC XML data and generate OWL classes.
• Uses rdfs:subClassOf to express ChildOf/ParentOf relationships between the CAPEC patterns.
• Includes related CWEs and ATT&CK techniques for each individual.
• Automates the integration of versioned CAPEC data using Makefile.
