- Support CSV exports from updated online banking interface introduced towards the end
of year 2023
- Simplify file parsing
- The importers now read all the lines in the file and treat the file contents before
the header as metadata and after the header as transactional data.
- Remove `file_encoding` parameter
- The older exports are always ISO-8859-1 encoded while the newer ones are UTF-8
encoded (with a Byte order mark at the beginning).
