hide (latex and other commands') log messages

Open3.capture2e ( https://docs.ruby-lang.org/ja/latest/method/Open3/m/capture2e.html ) を使って、コマンドを実行したときにエラーがでなければ標準出力・標準エラー出力へのアウトプットを行わないようにするものです。
なおエラーが出たときにはそれまでのログを全部まとめて吐き出します。

よさそうですが、待っている間に不安になりそうなので、
#962 的な実行中命令を出しておくといいんでしょうか。「running ’コマンドと引数’」とか?

[kmuto]

ってもうINFO実行は入ってたからいいのかな

現状では、成功すると、

review-pdfmaker config.yml
compiling nogeo.tex
INFO: extractbb cover.jpg
INFO: uplatex -interaction=nonstopmode -file-line-error book.tex
INFO: uplatex -interaction=nonstopmode -file-line-error book.tex
INFO: uplatex -interaction=nonstopmode -file-line-error book.tex
INFO: dvipdfmx -d 5 -z 9 book.dvi

といった出力になります。
