Feature request: store benchmark result & compare with file

[hazcod]

Hi, love the project!
Is it an idea to keep the previous bench result in a file, e.g. .github/cob.yaml and compare that?
This way you don't always need to re-run the benchmark twice, and it allows to compare against other branches than master.

We can store it, but I'm afraid that the bench score varies due to the environment since CI service launches a bit different environment each time. Do you have any ideas?

Maybe turn on/off with a toggle and store the result under .cob/ or so?
In theory GHA should have the same virtual instances:

Each virtual machine has the same hardware resources available.
