Reads Deckman CSV files.

Deckman may save data from multiple days into one file. For best results, make sure to only export data from one day.

Note: By default, the date format is expected to be dd/mm/yy or dd/mm/yyyy or yyyy-mm-dd. To load files with mm/dd/yy date format, change the date format configuration on your file to MDY when uploading it.

Also reads polars in Deckman format, and Deckman start files (D).
