Sanity check SigmetBetweenLatOrLon and SigmetOutsideLatOrLon parsing

[kasarit]

private static String re1="((N|S)\\sOF\\s([NS]\\d{2,4})\\sAND\\s(N|S)\\sOF\\s([NS](\\d{2,4})))";
private static String re2="((W|E)\\sOF\\s([WE]\\d{3,5})\\sAND\\s(W|E)\\sOF\\s([WE](\\d{3,5})))";

public SigmetBetweenLatOrLon(final OccurrenceFrequency prio) {
    super("^("+re1+")|("+re2+")$", prio);
}

@Override
public void visitIfMatched(final Lexeme token, final Matcher match, final ConversionHints hints) {
    token.identify(SIGMET_BETWEEN_LATLON);
    token.setParsedValue(ParsedValueName.RELATIONTYPE, match.group(3));
    token.setParsedValue(ParsedValueName.RELATEDLINE, match.group(4));
    token.setParsedValue(ParsedValueName.RELATIONTYPE2, match.group(5));
    token.setParsedValue(ParsedValueName.RELATEDLINE2, match.group(6));
}

Only groups of rel1 are being read here? It should be checked, if either group 1 or 7 is null, and then read appropriate groups.

The same logic applies for both SigmetBetweenLatOrLon and SigmetOutsideLatOrLon.
