[bug] Missing quotes for file path (with spaces)

[fritx]

The cmd line seems to break if a path like E:\Program Files\ passed in.

@fritx Do you still have any motivation for this?

I have little time to maintain this repo now. So I would like to add you as a collaborator if you want.

@uiureo yes, no problem!
Our team has been using this library for screencapture in our company IM, which has thousands of internal stuff as users.
And we have our own fork.
This lib is awesome 👍

@fritx thanks! added you as a collaborator 🎉
