[IMP] intrastat_base: A lot of imps:

* Add product_origin_country_id on declaration/computation lines

  Copy incoterms and destination country from SO to invoice when invoicing from SO
  We need weight even when supplementary units is used
  Small cleanups and enhancements

* Add support for accessory costs

  Add default values for intrastat transaction on company
  Code cleanup

* If rounded weight is 0, put 1

  Take into account the taxes for B2C
  Small code cleanup

* Remove field exclude_from_intrastat

  Re-organise view of intrastat.product.declaration

* Add option intrastat_accessory_costs on company

  Set more fields as invisible (localisation should put them visible if they need it)
  Fix handling of suppl. units when hs_code is empty on invoice line (but set on product)
  Small usability enhancements

* Warning -> UserError

* Inspired by the PR https://github.com/akretion/account-financial-reporting/pull/8 of Luc de Meyer

* total_amount is a sum of integers, so it should be an integer

  Add transport mode in computation tree view

* Demo VAT number should be on EU customers
