n26 has many different formats / mappings

[jaraco]

I find a project about import n26 into a plain text accounting tool: https://github.com/siddhantgoel/beancount-n26/blob/main/beancount_n26/__init__.py#L14.
The dict HEADER_FIELDS in the code confirm it exists few format for N26 statement. The original english mapping of csv2ofx is correct, my N26 statement is in fact a other format of english statement.
