Early stage of project, byt for simple case sales invoice it can create valid FA(2) from Json.

Current project stage limitation

• almost all annotations (except P_18) are hardcoded in converter
• only sales invoices are supported
• conversion of the invoice type was not consulted with a tax advisors (and still, only standard VAT invoice is supported)
• only payment by bank transfer and card is now supported

Sample input: gobl-ksef-converter/src/test/resources/invoice.json
