Raiffeisen Mein Elba: Improve parsing of Payee and Bank Account

[akirk]

This extends the parsing so that it now produces proper info for the payee, the bank account and the memo (just the Verwendungszweck).

Thx for your contribution! Just two nitpicks:

• Due to your change, the unittests fail
• Could you provide a (anonymized and minimal) CSV export as it is currently generated by Raiffeisen?

Could you please provide a minimal and anonymized CSV export from Raiffeisen that can be included to fix/update the tests?

[akirk]

@nblock sorry for the long wait, I've now added tests and fixed the existing ones.

I didn't know how to run unit tests, so here are some instructions of what I did:

I cloned https://github.com/kedder/ofxstatement and followed the test instructions there and then ln -sed the plugins directory from this repo and ran pytest from within the environment.

I just used this. It works well 👍 I am for merging it.
