Feature request: mechanism for (non-CI) extended tests

[mikeingold]

I recently implemented use of this package on MeshIntegrals.jl. It's great for PR's, but I try to keep limit CI runtimes. I'd really like to be able to define:

• a core set of benchmarks that will run in CI for all PR's, targeting a <10 minutes runtime, which means SUITE must be able to complete in <5 minutes.
• an extended set of benchmarks that I can trigger to be run on my local dev machine for a more thorough analysis.

I suppose this could currently be achieved by adding another benchmarks script and targeting it manually, but wasn't sure if there could be any broader interest in making a more explicit feature solution.

There is the --filter option which might help with this?

You could also set an environment variable and use that to conditionally add more or less tests to the SUITE group
