Title: Replace @out.print with @out.write to work better in dumb terminal (Emacs)

Please consider to apply this little patch. I tried to use ruby-progressbar inside Emacs' M-x shell terminal and it does not show progressbar, only final value.

Basically, I am not user what is the difference between IO#print and IO#write, but write fixes this issue completely. I found this method in other gem progress_bar.

Thank you!
