This update integrates Viettel SInvoice, a Vietnamese e-invoicing system, directly into the Point of Sale module. This allows businesses using the Odoo POS system to automatically generate and attach required e-invoice documents for compliance with Vietnamese regulations, streamlining the invoicing process. The changes improve the system's ability to handle e-invoicing requirements for Vietnamese customers.

Add Viettel SInvoice integration with the Point of Sale module to support PoS e-invoicing for the Vietnamese market.

This update integrates Cashdro cash machines into Odoo's point-of-sale system. Because Cashdro machines communicate via HTTP, no new hardware is required, streamlining the integration. This allows users to accept payments directly from Cashdro machines, improving payment flexibility.

This commit adds support for the Cashdro line of cash machines. These work via HTTP so they do not require any additional hardware, and can be used with LNA to avoid the need for a certificate.
