Improve the fio package

[safl]

• Add the cijoe fio package to package testing / verfication
  • That is, include it in the cijoe_packages github action workflow
  • See: feat(gha): add verification of the cijoe package, fio #125
• Add example (config and workflow) showing how to run / use the fio wrapper
  • Consider simplifying it dramatically, it is currently very convoluted
  • Note: it must exercise the different ways that fio engines are handled e.g. builtin / external / etc.
• Update documentation for the fio package

@safl as far as I can see, there are example workflows and configs for the fio package, added the same day as this issue was opened. Are these okay now that the fio package has been trimmed down or do we need to modify them?

Additionally, does the documentation need to cover more?

If the example workflows and configs cover all scripts and modules, they are sufficient. Otherwise, additional content is needed. In general, coverage should include all scripts and modules, making the setup self-contained.
