Use log_static() for constant data in DNA example.

What

Just a tiny little thing that was bugging me: the DNA example now uses log_static() for all the non-animated data logged at the beginning. This gives better results when viewing with a time range query — otherwise the left, right, and scaffolding always disappear if the time range doesn’t include the beginning of the recording.

Here is the new appearance with a 0.5 second time range; previously, only the gray points would be visible:

Nice -- I've been meaning to do that for a while.

log_static is deprecated though, lemme fix that. Oh wait this the Rust example.

I want it too. But if we do it we need to do it on all three DNA examples (python, cpp, rust)!
