Add codspeed performance testing to CI

[jqnatividad]

The number one goal of qsv is to be the FASTEST command-line, data-wrangling kit for tabular data.

For this is the only way we can infer automagical metadata - near real-time metadata inferencing in CKAN, DP+, qsv pro, etc.

We already have benchmarks, but that tracks performance on release.

With codspeed, we should be able to track performance between releases, as we develop qsv.
