Reindent current top level form after >> or <<

[DogLooksGood]

It's very nice to have << and >> that adjust indentation automatically. and It's will be more convenient if indent always following the indent that provide by clojure-static.

There's some overlap here: https://github.com/clojure-vim/nvim-parinfer.js/issues/23

But these mappings https://github.com/clojure-vim/nvim-parinfer.js/blob/master/plugin/parinfer.vim#L86-L89 need to be able to be turned off so users can do something like autocmd FileType clojure,scheme,lisp,racket :nmap <buffer> << <Plug>ParinferShiftNormLeft=-
