> Allow multiple events to be captured simultaneously in this version,
> provided that JFR is chosen as output format.
> Delegate output file writing to the async-profiler. This is required
> in 2.x for the JFR output but is supported in both versions. The file
> path must be provided when starting the profiler with JFR output, so
> we need to create the per-trial output directory in the first
> `beforeIteration`.
> Avoid the character '%' in the generated directory name as this
> is interpreted by async-profiler as part %p or %t placeholder.
