Performance reporter

We currently run benchmarks and manually add the results from CI to a table when feel right.

Instead, the idea is to add CI which
1) Would run the benchmark
2) Push the resulting `result.csv` into `AngouriMathLab/performance-reports`

Then, make a program in `AngouriMathLab/performance-reports-tools` based on Plotly.NET which would
1) gather all reports from `AngouriMathLab/performance-reports`
2) build graphics for each one and export them into diagrams
3) Push the result to `AngouriMathSite/master` with the diagram onto `am.angouri.org/performance-reports`
