Flag data folder to *not* DELETE #18
Description
Currently the DELETE flag can be set to TRUE or FALSE. Would it be possible to target a specific folder in the dataset to skip if the DELETE flag is set to TRUE?
A common use case would be to upload code files from GitHub to Dataverse, but add data files separately. When a new version of the code is released and triggers an update of the Dataverse dataset, it would be great to have all of the files from GitHub be deleted and the new files uploaded to the dataset (as how it currently works), but allow the user to add a flag to the YML file targeting folders to NOT delete. This allows the user to avoid having to upload the same data files to the dataset for each version update.
