Please add sane-airscan and ipp-usb packages to my upload rights into main

[Till Kamppeter]

Hi,

I have per-package upload rights for printing-related packages.

I am maintaining the following packages which made it into Main recently:

- sane-airscan
- ipp-usb

They are part of the driverless printing and scanning infrastructure.

Could you give me upload rights into Main for these ones? Thanks in advance.
