fix SFINAE error; now compiles and runs with gcc-9 #28

Address issue #25. @agrawalparth10, please take a look and see if you can compile on Mac OS. If you don't get this error (but still get others), I will still go ahead and merge.

The SFINAE was fixed on clang 12.0.0.

I got the following error - no template named 'unordered_map' in namespace 'std'

This was fixed by adding #include <unordered_map> in common/timer.h
