This pull request (PR) facilitates the integration of Odoo with the Uruguayan electronic billing system, allowing automatic synchronization of vendor bills every 10 minutes. Synchronized bills are created in "Draft" status for user review, complete with attached PDF and XML files.
Also this pull request allows to create vendor bills from XML files on uruguayan journals.

**Key Features**:

- **_Automatic Bill Creation_**: Bills are generated in "Draft" status to enable manual verification against vendor invoices and attachments.

- **_Necessary Configuration_**:
1) The database must connect to Uruware.
2) A Uruguayan company must be set up with an appropriate chart of accounts.
3) Notifications must be activated in the Uruguayan billing system.

**Important Considerations**:
- Errors during synchronization will still create invoices in "Draft" with error messages for user review.
- Invoice lines are created without products; if a vendor doesn’t exist, it will be automatically created based on RUT.
- Any unregistered taxes will be flagged.

**Technical Overview**:
- **_Notification Mechanism_**: Notifications for each received CFE are managed through a web service, allowing users to check, request details, and discard notifications.
- **_Synchronization Process_**: Notifications are read and processed sequentially, with each CFE generating a corresponding document in Odoo. Notifications must be discarded to continue processing.
