Allow more than 4 decimals

[nicolassalo]

First of all, I am very glad to see that version 17 brought an update to use 4 decimals instead of 2. I got some concerned emails from accountants complaining about rounding issues of invoice totals vs line totals and it was fixed after updating to the latest version. While this issue is now fixed for 99.99% of invoices, would it make sense to increase this number even more? I created an example invoices in sevdesk and saw that they use 8 decimals in their xml.
