new packages: libraries for the 'puredata' package

[Alexandre Quessy]

Hello Hans and the team,
I think this team is the right place for the puredata-related
packages. This is great news. APT is an awesome package manager. That
is good for the Pd externals and abstractions, for which the packaging
has always (?) been an issue, and Hans has done tremendous efforts to
overcome this. I will follow this up. Though I am not currently much
using Pure Data, I might be of some help as I am in the team. (not a
DM yet, though)
