Add benchmarks for jsoniter-scala

[plokhotnyuk]

@sirthias Thanks for the bench suit! So diversive workloads!

JFYK, I have found that Borer 0.9.0 outperforms jsoniter-scala 0.47.0 in parsing of some messages where case classes have too many fields to parse in a hot-loop (~90 or more, like in reddit-scala.json).

Also, it helped to find an issue with case classes that has 32, 64, etc. fields

Bellow are results of both parsers on my notebook with OpenJDK 11:

Another finding that for different JVMs results can differ in ~2 times on some workloads (like serialization of eu-lobby-country.json or parsing of reddit-scala.json):

Yet another finding is that turning off of hyper-threading improves results of some benchmarks (see encodeModel eu-lobby-country.json, and encodeModel movies.json):

[info] REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on
[info] why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial
[info] experiments, perform baseline and negative tests that provide experimental control, make sure
[info] the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts.
[info] Do not assume the numbers tell you what you want them to tell.
