RBA - many datasets are not converted

https://git.nomics.world/dbnomics-fetchers/rba-fetcher/-/jobs/161090

Many errors like this one:

INFO: - sheet: 2014
WARNING: 'E3-1' dataset aborted ! - unexpected fields in file header:
('title', 'description', 'frequency', 'type', 'units', '', '', 'source', 'publication date', '') != 
('title', 'description', 'frequency', 'type', 'units', '', '', 'source', 'publication date', 'series id')

prevents datasets from being converted
