Allow to specify encoding and destination path of the output file

[tchiavegatti]

Thank you for developing this, it seems to be a very useful tool. However, when converting a xlsx file to csv with gocsv xlsx, it would be great to have the option to specify the encoding of the output `csv file.

Also, when doing a batch conversion of multiple files, it would be nice to be able to specify the destination directory for the output files instead of creating a directory for the CSVs.

Hi @tchiavegatti, can you clarify your comment?

The xlsx command already has the -dirname option. Please provide details on what more you need; given the nature of XLS files having multiple sheets, please include an example that shows your need and how GoCSV currently doesn't meet it.

Regarding the encoding of output files... I don't think this is a good fit for GoCSV. You could try piping the output (or input) to something like iconv. Or, here's a solution I wrote up on StackOverflow for using Go and the experimental text package to convert between UTF-8 and popular code pages (encodings), https://stackoverflow.com/a/76784010/246801. I've codified all that in a simple text transcoding tool, gotxt.
