Add automated benchmarking

[peytondmurray]

This PR adds automated benchmarking on GCP via Cirun:

• Added .cirun.yml configuration. Seems to be working well already 🎉
• Made a benchmarking workflow that pushes results to master. When the docs build, the asv results are rendered into static HTML. A link to these is added to the front page of the docs
• The benchmarking install code has been greatly simplified
• Reduced the number of versions in the delete_version benchmark; it was taking way too long

Closes #343.

This was tested with a pure python version of build_data_dict, as the current one is broken on CI and my local machine: https://github.com/peytondmurray/versioned-hdf5/actions/runs/11391825172

@peytondmurray I think it would be incredibly useful to be able to rerun asv on a controlled environment (GCP) on a PR before it gets merged and compare the results. Do I understand correctly however that this PR can exclusively run in master? Would it be a sensible followup to add the functionality to do a comparative benchmark on an open PR (maybe triggered by a github PR tag)?

Sure, this is definitely possible - especially if you're fine with just a table of benchmark results as output. I can follow up in another PR with a bot that posts benchmarks in a comment, if that makes the most sense.

Here's the latest version, I merged this PR into my own fork's master to trigger the build: https://peytondmurray.github.io/versioned-hdf5/benchmarks/index.html

I think the graphs aren't displaying correctly because there's only one data point (the latest commit comparison), but it could be that master~1 doesn't have the H5Close commit, so the benchmark failed. Anyway that's not terribly relevant as the machinery there is being changed out soon anyway.

@peytondmurray it's failing in master:

1. still the dcpl.id not being found, and
2. something about git permissions when you try pushing

You're installing libhdf5 from conda and h5py from pip. Could you try moving h5py to conda too?

[peytondmurray]

Yep, will do now.
