khayyam Pre Build

a common problem with khayyam python library is The C extension is not available. Switching to fallback python pure algorithms error which makes it slow. The solution is to build the library from the source and use it, instead of installing it with pip. But if you don't want to (or can't) build it, you can use the pre-build files which I prepared. Just extract the right version (3.6, 3.7 or 3.8 beased on your python version) zip file in the site-packages folder where your python or virtual env is installed. the khayyam folder in the zip file should be in your site-packages folder.
