Sorting: add outlier detection as a sorting option

[matyax]

This PR adds outlier detection to sort value breakdowns. It works by using DBSCAN to detect outlying intervals, and sorting by the detected quantity.

Addtionally, we're wrapping all the WASM invocations, logging the errors and falling back to StdDev when it happens.

I think we need to also gate

explore-logs/src/module.ts

Line 8 in 85085a9

init().then(() => console.debug('Grafana ML initialized'));

to only init when wasm is supported.

Right! Great idea, done.

LGTM and working well locally
