Adds Windows support and AppVeyor CI (#835)

* Get miasm to work on Windows, also add AppVeyor CI

* Fix gcc jitter on Linux

* Make the dse_crackme tests work on Windows

* calling build and then install is less confusing than install twice

* fix os.rename race condition on Windows

* clean it up

* Clean up after the unused cl.exe's artifacts

* Use is_win instead of an additional check

* Fix issue on Windows where 'w' and 'wb' modes are different

* Address review feedback

* setuptools is actually not required, so reverting
