Support IE 10, 11

Currently I use the library and I have a problem to put it to work on Internet exploret 10, 11, Edge, to solve this problem, all you have to do is organize the methods of EMSC6, you can try creating a simple project integrating the library and in the additional package.json:

     "@ babel / core": "^ 7.4.5",
     "@ babel / polyfill": "^ 7.4.4",
     "@ babel / preset-env": "^ 7.4.5"

Note: The above I propose because I like this liberia and I do not want to eliminate it in my new projects, I hope I take the contribution and they can solve it as quickly as possible.
