Currently, the delimiter on e.g. the multiselect_list is a single string.

We face the case where some users have comma-separated CSVs with semicolon as delimiter for multi-select lists, others have semicolon-separated CSVs but with comma separated delimiters 🤷

Ideally I would hand over a list of delimiters, and CSV-Box reduces the potential delimiters for non-apostroph (like '...,list_item_1, list_item_2,...'contents to use only the delimiters not being used for the CSV-file columns itself. For apostrophed contents (like '...,"list_item_1, list_item_2",...')
