Added integrity checks for prebuilt binary files to eliminate the chance of man-in-the-middle attacks
Added experimental support for Raspberry Pi (Precompiled binaries for linux on arm are provided)
Switched to using node-gyp for binary compilation when prebuilt binaries are not available. This will provide better support for alternate versions of Node such as Electron, for which prebuilt binaries are not provided
Added DLL version information to the Windows Node binary
