Adding New Inductor Patterns

1. In the manufacturer handler's initializePatterns():

registry.addPattern(ComponentType.INDUCTOR, "^NEWIND[0-9]{4}.*");
registry.addPattern(ComponentType.INDUCTOR_CHIP_MANUFACTURER, "^NEWIND[0-9]{4}.*");

1. Add to getSupportedTypes():

types.add(ComponentType.INDUCTOR);
types.add(ComponentType.INDUCTOR_CHIP_MANUFACTURER);
