Use BenchmarkDotNet

Love this benchmark!

Change the custom benchmarking infrastructure to use BDN, it's the de-factor benchmarking tech for .NET projects now and it'll likely produce more accurate results and more detailed measurements (like allocations etc).

Wow that’s pretty awesome. Also some of these containers are near native speed (same as without a container), I need to see what they do under the covers.
