Provide Path/URL in CSV reading exceptions

Try running this code that contains a user error in URL:
`DataFrame.readCsv("https://github.com/Kotlin/dataframe/blob/master/data/jetbrains_repositories.csv")`

Proposed:
Let's catch CsvReaderException and re-throw our own exception with URL + original exception as cause. Maybe clickable URL will prompt user to check actual content and see that in fact this is not direct link to CSV, but to a GitHub page. IMO all our reading functions should follow this idea

Start by tracing CSV errors through impl/io/readDelim.kt, io/ReadCsvDeephavenKt/readCsv.kt, and io/common.kt, using the stack trace as the entry point. Check how the reading functions propagate CsvReaderException and add coverage for the supplied GitHub URL case; done means the resulting exception includes the source URL while preserving the original cause.
