[IMP] add support for PAIN 001.001.09 + 008.001.08 (adopted by EPC)

Remove support for:
- SCT : pain.001.001.04, pain.001.001.05
- SDD : ain.008.001.03, ain.008.001.04
because these PAIN version have never been adopted by EPC.

 Module to export payment orders in SEPA XML file format.
 
-SEPA PAIN (PAyment INitiation) is the new european standard for
-Customer-to-Bank payment instructions. This module implements SEPA Credit
-Transfer (SCT), more specifically PAIN versions 001.001.03,
-001.001.04 and 001.001.05. It is part of the ISO 20022 standard, available on
-https://www.iso20022.org.
+`ISO 20022 <https://www.iso20022.org/>`_ is the new international standard for
+bank XML files. This module implements SEPA Credit
+Transfer (SCT), more specifically ISO 20022 PAIN (PAyment INitiation) versions 001.001.03
+and 001.001.09. It follows the `SEPA credit transfer implementation guidelines <https://www.europeanpaymentscouncil.eu/what-we-do/epc-payment-schemes/sepa-credit-transfer/sepa-credit-transfer-rulebook-and>`_ of the `European Payments Council <https://www.europeanpaymentscouncil.eu>`_.
 
-The Implementation Guidelines for SEPA Credit Transfer published by the
-European Payments Council (https://www.europeanpaymentscouncil.eu) use
-PAIN version 001.001.03, so it's probably the version of PAIN that you should
-try first.
+This module also supports PAIN version 001.003.03 which is used in Germany.
+You can read more about this in german on `ebics.de <https://www.ebics.de/>`_.
 
-It also includes pain.001.003.03 which is used in Germany instead of 001.001.03.
-You can read more about this here (only in german language):
-http://www.ebics.de/startseite/
+Moreover, this module supports:
+
+* SEPA **instant** credit transfer,
+* non-SEPA credit transfer files, which can be used for wire transfer in currencies other then euro and/or to countries outside the `SEPA zone <https://en.wikipedia.org/wiki/Single_Euro_Payments_Area>`_.
