[Debian-med-packaging] Sponsoring many uploads

[Kevin Murray]

Hi all

I have many updated packages that need an upload. These are:

- axe-demultiplexer: fix vcs-git url
- python-skbio: new upstream release
- scythe: Fix d/watch
- libzstd: New upstream release w/ FTBFS bugfix

Also, many thanks to Andreas for beating me to update Stacks.

(P.s. sorry to dump these like this, I've been queueing them till I get DM
status, but that won't be for a while so better upload them now)

Thanks,

Kevin
