Make address validation configurable per address field, per country

Current problem: Canadian postal codes need to be in a specific format for upload to our distribution third party. As we do not have validation currently in place within Limio, we receive postal codes which fail and need to manually correct them. Volumes are low per week (<50) and must be fixed manually. If postcodes aren't fixed, the whole Canada file fails and all Canada copies could be delayed.

Feature request: The aim of this is to introduce postcode validation both at acquisition and delivery address entry/update. We were trying to use this documentation to configure, however it only allows you to implement validation rules across the whole country address form, not within specific address fields (like the post code). We would like to request this level of granularity as a new feature.
