`std::error:Error` is not implemented for `XlsxError` in `umya_spreadsheet::reader`, and `umya_spreadsheet::writer`

I tried to use error propagation with Box<dyn std::error::Error> with the read and write methods and found that std::error::Error was not implemented for XlsxError.

Is there a different preferred way of handling these errors or should std::error::Error be implemented for these?

Thank you for contacting us. Implemented std::error:Error in XlsxError. Please get the latest version and check it.

Tested version 0.8.3 and error propagation with Box is now possible. Thank you.
