Add benchmarking via perf protocol

[flcl42]

Libp2p community provides a great tool to test typical protocol stacks performance:
https://github.com/libp2p/test-plans/tree/master/perf.
Example of run: https://observablehq.com/@libp2p-workspace/performance-dashboard.

We have all protocols needed to participate in the benchmarks.
Let's add dotnet-libp2p to the benchmarks and optimize our code to become the most performant ones 🥳
