Adds the pipeline for dataset A14 (#35): Regional indicators of the Tourism Satellite Accounts by canton and product and Year

Due to the complexity of the dataset, a subset of products and indicators have been selected. A14 is only meant to show the importance of tourism in the local economy of each canton in terms of "gross added value" and "employment".

More detailed products such as the sectors of tourism (sport, travel agencies, restaurants, ...) were excluded. If we consider them important, they could be made into a separate table.
