Upload to bookworm-backports

[Alec Leamas <leamas.alec@gmail.com>]

Dear mentors,

I'm trying to upload openpcn to bookworm-backports. Since I'm just a DM, 
I need a sponsor to upload the first package heading into the NEW queue.

However, bookworm-backports is yet not accepted by the mentors 
infrastructure. Is there any other way I could get some help with this 
upload?

The package is available at https://gitlab.com/leamas/opencpn in the 
branch debian/bookworm-backports. The delta against sid is as expected 
minimal.

Cheers!
