libs/rocket: add GNU Rocket submodule

Preparatory commit for experimenting with a GNU Rocket
integration for controlling the stream pipes on a timeline.

Since rocket doesn't support things like arbitrary strings, it's
not a natural fit for rototiller where the obvious thing would be
to describe scene compositions as settings strings as if you were
invoking rototiller.

But a temporary hack might be to just tell a rocket module
up-front all the scenes as settings strings you provide to its
setup.  Those get assigned numeric identifiers, then rocket
tracks can control when they come on/off numerically.  It just
requires describing all the scenes up front rather than in the
pattern editor which is less than ideal.

Being able to experiment with this half-ass solution may prove
useful anyways, and shouldn't be too much work.
