feat: Add UK driving licence number recognizer

[tee-jagz]

Add UkDrivingLicenceRecognizer for detecting DVLA driving licence numbers. The 16-character alphanumeric format encodes surname, date of birth, and initials. Uses regex with embedded month/day validation and surname padding checks. Disabled by default per country-specific convention.

Change Description

Add a new country-specific recognizer for UK driving licence numbers (entity: UK_DRIVING_LICENCE). The recognizer detects 16-character DVLA licence numbers using regex pattern matching with context words and structural validation of the surname padding. The DVLA check digit algorithm is not public, so validation rejects clearly invalid patterns but does not confirm validity.

Files changed:

• New: uk_driving_licence_recognizer.py — recognizer class
• New: test_uk_driving_licence_recognizer.py — 21 tests
• Updated: default_recognizers.yaml, __init__.py exports, supported_entities.md
• Updated: default_recognizers.yaml — registered with enabled: false
• Updated: supported_entities.md — added UK_DRIVING_LICENCE row
