Add a simple benchmark suite

[schneiderfelipe]

This adds a simple benchmark suite (resolves #19). A simple report can be generated as well, with graphs such as

The report can be generated with

julia> include("benchmark/benchmarks.jl")
savereport (generic function with 2 methods)

julia> savereport(run(suite))

Most of the benchmarks are very naive and would benefit from critical feedback.

Hey,I generally think the Julia project's benchmarking practices are inadequate to correctly evaluate the impact of code changes, in particular the focus on minimum times, and stand by my comment about being surprised if Hyperscript offers performance advantages over any package specifically written to have good performance. :)

I'm also increasingly not the best person to continue to maintain this package, as I haven't used Julia's web ecosystem in a long time. I wonder if there's a possibility of having maintainership taken over by e.g. the folks at JuliaWeb...

That's OK. I understand your point. How could I change this PR to reflect a better way of evaluating the impact of code changes?

This could change in the future. #13 is an example. I'm interested in working on improving the performance of Hyperscript.jl, if you don't mind. But, for that, a way of measuring performance is required.

@yurivish Is there someone we could talk to to make this transfer? I could send a message to #web Slack, if you don't mind.

Sure, thanks @schneiderfelipe.

The biggest improvement would be showing distributions instead of individual measurements. E.g. each test could instead be shown as a be a collection of tickmarks

or a violin plot visualizing the distribution of timing values for each test.
