[FIX] l10n_sa_edi: Fix QR code extraction from XML content

QR code extraction fails in some cases when we try to get the Base64 content
from the Saudi EDI attachment when the datas is too voluminous. To avoid this, we pass
bin_size=False in the context to always get the attachment datas correctly.
