Create webform File Upload Element for Frictionless Data Packages about webform_strawberryfield

[DiegoPino]

Yes. This is needed.

Ok. So a few thoughts:
1.- We want that Frictionless data packages can also be generated via a Drush API ingest.
So actually the special field will do the following:
1.- Simply upload the files but also "mark" them in the JSON (an ap: prefixed key of an flv: prefixed key need ) to be Packaged once the ADO is saved.
2.- We may need then a Post processor that does that.
3.- Once packaged, and if people want to edit the ADO (they will) people will be able still to remove/add files to the existing package (so they should never see the package, just the individual images).

All this requires logic, patience and testing. But so needed.
