Example for SEPADirectDebitBasic.php is broken because of changed nemiah\phpSepaXml library

[Cugar15]

1. The used nemiah\phpSepaXml library was changed. Type was move from the SEPADirectDebitBasic to the addDebitor defintion
2. Type was changed from COR1 to CORE since COR1 does not seem to work
3. The default pain format pain.008.003.02 is no longer valid and hence the call to toXML the current format pain.008.001.02 was added to overwrite the default.
