Issue:
[QUESTION] Accessing Node ReceivableSpecifiedTradeAccountingAccount
First of all I wan't to thank you from the bottom of my heart for your commitment and this awesome project. 

My question is: Can you estimate when the functionality around _TradeAccountingAccount_ will be implemented?

Specially the Field _ReceivableSpecifiedTradeAccountingAccount_:

```
...
<ram:SpecifiedLineTradeSettlement>
    ...
    <ram:ReceivableSpecifiedTradeAccountingAccount>
        <ram:ID>1337</ram:ID>
    </ram:ReceivableSpecifiedTradeAccountingAccount>
    ...
</ram:SpecifiedLineTradeSettlement>
...
```

Example: [factur-x.zip](https://github.com/user-attachments/files/19179807/factur-x.zip)

You've commented your code as a reminder:
ZugferdDocumentReader.php (Line: 3923)

Best regards
