feature request: Get function for SellerTradeParty name

[GorillaEXP]

Hello,

i just started to learn how to use this project and used the example from the website:

https://www.mustangproject.org/use/
ZUGFeRDImporter zu=new ZUGFeRDImporter("MustangGnuaccountingBeispielRE-20190610_507.pdf"); System.out.println("Total amount: "+zu.getAmount());

It works fine so i tried to get more data elements from the invoice and most work, but i could not find a get-method for the name of the SellerTradeParty that is written in the xml of the invoide like this:
<ram:SellerTradeParty> <ram:ID>some_id</ram:ID> <ram:Name>some_company_name</ram:Name>

Is the function missing or am i doing it wrong?
