docs: allow docs to build on windows (#49)

Warning: Docs hosted for public consumption should still be built from Linux.
This patch simply allows building docs from windows for limited inspection.
Some API docs (eg. `RF24` or `FakeBle` classes) will not be rendered correctly (if at all) since the underlying bindings only compile for Linux.
