Would it be alright to add benchmarks?

[Laifsyn]

I was doing some benchmarks while writing stuffs up, but because I wasn't as expertised on this aspect, I deleted everything. However, it does work by accessing the library as a Lib User, so to test inner logic, you would have to either copy and paste it out of the private modules, or expose methods to test.

I have used Criterion, but it seems there's probably more appealing options like Bencher, which seems to support CI benching (Whatever that is) https://nnethercote.github.io/perf-book/benchmarking.html
