[IMP] snailmail: adapt reports for snailmail

In order to ease the integration with the snailmail posting service provider,
We will generate specific reports with a layout that fits their
criteria.
In short,
* we specify the postition of the recipient's address on the
document
* we force the A4 format

This also support the din5008 type B report.
