fix missing import-package

The file SonosXMLParser.java is using the following imports:
- org.xml.sax.Attributes;
- org.xml.sax.InputSource;
- org.xml.sax.SAXException;
- org.xml.sax.XMLReader;
- org.xml.sax.helpers.DefaultHandler;
- org.xml.sax.helpers.XMLReaderFactory;

The OSGi specification mandates that a bundle declare all package
depenencies using either Import-Package or Require-Bundle. The one
exception to this rule is the java.* packages which is always delegated
to the boot classpath. All other packages dependencies must be declared
in the bundle's manifest file.
