bench: add gitignore file for profile outputs

[EdmundGoodman]

Add gitignore file for profile outputs in response to comment

[EdmundGoodman]

Hopefully an uncontroversial one to start with...

Will work out a good order to get more stuff in next. The seemingly obvious place to start is the bench_utils.py profiling stuff, but that is quite transient as I am adding stuff like bytecode visualisation, so perhaps some other benchmarks might be better?

What is the best way to do this? I've linked back to it in the first comment and there is a mention link in the thread -- is there a good way to put it in the title or similar?

I think just clearly saying "Peeled off from #XYZW" in the initial comment is more than enough, and it links both PRs automatically.
