This is a definite work in progress. In particular, * there's no src/web.rs support yet so it can't be used, * the code is surprisingly complex, and there's almost no tests so far. I want to at least get complete branch coverage. * I may still go back to time_sec rather than time_90k to save RAM and flash. I simplified the approach a bit from the earlier goal in design/api.md. In particular, there's no longer the separate concept of "observation" vs "prediction". Now the predictions are just observations that extend a bit beyond now. They may be flushed prematurely and I'll try living with that to avoid making things even more complex.
