fix: Remove unused import of windows.h

[rotu]

Fixes #199 by not including the header with offending min/max macros.
Alternative fix to #208.

[rotu]

Note this may not fully fix the issue in some cases. electron-gyp is still injecting windows.h for me via .electron-gyp\34.0.0\include\node\v8-internal.h. This might also be because @electron/rebuild is pulling in an old node-gyp per electron/rebuild#1157.
