Parameters (Custom fields) for items is used in our project, therefore I added the possiblity to add these to document items. I hope it won't be against your way of using this lib, but honestly the change is very subtle. I allowed the item to return Riesenia\Pohoda\Document\Part instead of $this and added use AddParameterTrait.
Other minor tweaks
Allow histRate field for Orders
Allow percentVAT field for IssueSlip + allowed rateVAT values
Allow parameters (custom fields) for items
