This update adapts the French FEC import process to recent changes in the Odoo community. The system now streams data from the FEC file instead of using a previous field, ensuring compatibility and improved efficiency. This change supports ongoing compliance with French accounting regulations.

This commit aims to adapt the usage of 'account.fr.fec' to the changes made in community.

In particular `fec_data` field is not used any more. and we use `_get_fec_stream` to stream the content of the file.
