[Tf_address_check] Update

Good morning Task Force,

attached you can find a report summarising our recent improvements on the address-checker. Currently we are working on FR, UK, CH and IT and it looks promising to increase those also in average by 10%. If you do not have already, please add your countries address characteristics to the repository: https://gitlab.centr.org/centr/address-check

As a next step, we want to invite you for a review and discuss all functionalities in detail with you in a zoom call. But in advance, we would like to gather your opinions: Who may be interested to run the service on their own hardware? Who would be interested to use a service provided by Denic?

Kind regards Robin Gontermann
