Persistent readonly perfect hash table: benchmarks

• Write benchmarks measuring performances for contents in the order of 100GB and 10 millions entries
• Include the benchmarks in the python package
• Functional tests of the benchmarks to run in the CI
• Run the benchmarks on grid5000 hardware and archive the results

Outcome:

• A repository tree containing (i) instructions to run the benchmarks, (ii) the software to run the benchmarks
• The grid5000 results added to the repository at a tag marked with the date at which they were run
