[Pkg-rust-maintainers] Migration of block-padding

[Alexander Kjäll]

No need to say sorry for the blocking of packages, this is what the
packaging work is all about after all :)

Another datapoint in this situation is that Jonas have asked for
multihash to be upgraded to 0.19, and that would remove the need for
the sha3-0.9 package.

I'm happy to help out if you need any help, but don't know with
exactly what if you are also planning to look at it, maybe I can take
a stab at upgrading multihash to 0.19 unless someone else is working
on that.

best regards
Alexander Kjäll
