Automatic benchmarks via Github workflow

[St-Maxwell]

I created a repository (St-Maxwell/benchmark) with the use of Github workflow to perform automatic benchmarks and publish the results to Github page. I imitated Julia's Microbenchmarks to accomplish this prototype.

By working with my automatic benchmarks, I think fortran-lang/benchmarks require the following tasks:

• a basic framework of benchmark for each language
• workflow of automatic benchmarks (and deploying github page)
• documentation

I believe my repository is helpful for the first two tasks. Of course, it needs further polishing. So I'd like to hear your suggestions. Thanks!

Thank you! Indeed, it looks like a good basic framework to automate display.
