[17.0][ADD] ``account_banking_international_credit_transfer``
Add a new module to manage international credit transfers.
This adds the possibility to add an Intermediary bank on a res.partner.bank. When generating the pain file for an International Credit Transfer payment method, the intermediary bank account info will be added in CstmrCdtTrfInitn > PmtInf > CdtTrfTxInf > IntrmyAgt1 > FinInstnId
For now the module only supports pain.001.001.03
A lot of the code is very close from the module account_banking_sepa_credit_transfer: since a lot of copy/paste have been done, we've kept the Copyright of the original module
Also rename finalize_sepa_file_creation into finalize_pain_file_creation. Indeed, this method can also be used for non-sepa pain files
