Any interest to introduce event library libhv into libverto as backend?

[he7850]

There is a high performance event library called libhv. It has faster implementation about event loop functions, see https://github.com/ithewei/libhv#-benchmark

libverto has encapsulated libev, libevent as backend, suggest to include libhv as well. if it is okay to introduce libhv into libverto, I will try to submit a commit.
