Summer is a dead season, but we can still push out a simple patch
release. JMH 1.10.4 is available, thanks to Evgeny Mandrikov, as usual.

Summary of changes:

 * perfnorm would have failed to produce results on perf 3.13. This
regressed at 1.10.3, and fixed:

gather unsupported events. This regressed since 1.10, and fixed now:

 * New option to list benchmark with parameters (-lp). The patch was
contributed by Sergey Kuksenko:

 * New samples: BranchPrediction and CacheAccess. These samples describe

performant. Ideas and initial implementations were contributed by
Michael Mirwaldt (with some polishing from yours truly):

 * New sample: PerInvokeSetup. This sample describes how to deal with a
