When describing data with metadata csv delimiter is fixed to ";"

[jh-RLI]

Description of the issue

Here we hardcode the column delimiter to a ";" this might not always be the case as some want to use a ",".

Ideas of solution

Move the delimiter option to parameter to let the user decide what they want to use. Or use the CsvControl from frictionless.
