Windows EulaHash calculator in Go. Useful if you want to know the hash of a public build for whatever reason.

For those unfamiliar with confidential Windows pre-release builds, here's all the info you need:

• Looks like this: [rest of build string].c0e1af437cb0d038, visible on the desktop watermark as well anything using ShellAbout (such as winver) on confidential builds.
• Calculated from the default value of \WPA\478C035F-04BC-48C7-B324-2462D786DAD7-5P-9 in the registry.
• Present from ~79xx Windows 8 builds until Windows 10 1511 (yes, even in public/RTM builds).

Based on research and code from Lucas.
