scoop manifest for windows users

• Firstly thankyou to the developer(s)
• Consider submitting a scoop "app manfest file" to make it even easier for windows users to install xxhsum
• scoop [1] is a package manager for windows that automates the version checking, downloading, installing in a portable way for unprivileged users and doing the the install/update.
• It could go into the scoop extras bucket perhaps.
• See [2][3] for info and examples on manifest files
