`query.py flame '<TraceQL>' [since] [out.svg]` folds the matching spans of up to
100 traces into stacks of self time and draws them as a flame graph, with the
folded stacks beside it for speedscope or inferno. A wall-clock picture of where
a route's time goes, waiting included, which a CPU profiler would not show: ipx
waits on Postgres and the disk far more than it computes. The traces are fetched
in one container, a docker run apiece being a second each.
