* add aggr model to peak models
change convolve with first pattern.
now it is avarage model instead of only first pattern.
* common model for peaks with comments
- Subtract min value from dataset before passing to model
- Rename StepModel -> DropModel
- Use cache to save state in all models
- Return `Segment { 'from': <timestamp>, 'to': <timestamp>}` instead of `Segment { 'from': <index>, 'to': <index>}` in all models
- Integrate new peaks model (from https://github.com/hastic/hastic-server/pull/123)
- Integrate new reverse-peaks model (from https://github.com/hastic/hastic-server/pull/123)
- Refactor: make `predict` method in `Model` not abstract and remove it from all children
- Refactor: add abstract `do_predict` method to models
