All of the IE11 bugs

[grug]

Describe the bug
This library doesn't work with IE11 at all. This is due to the right polyfills not existing.

To Reproduce

1. Create a new project with data-mocks included
2. Attempt to load up a page that uses data-mocks in IE11
3. Observe a million console errors

Expected behavior
That this library works as intended with IE11

Additional context
There will need to be a fair few polyfills added for this :(

This issue hasn't received any attention in a while. Can it be closed or does it require more work?

it would still be nice if we could use this library in IE11...

@Dinosys I'll see if I can give this a look today!

I've got this working in a clean create-react-app project. I had to add the following polyfills to the project to get it working on ie11 without data-mocks included:

import "react-app-polyfill/ie11";
import "react-app-polyfill/stable";

However the only error I could attribute to data-mocks was Proxy is undefined which was caused by the fetch-mock library using Proxy which is unsupported by ie11.

This can be solved by a rollback to fetch-mock 6.5.2
wheresrhys/fetch-mock#415 (comment)

Definitely not seeing loads of console errors though.

N.B I've yet to test graphQL

I've looked into IE11 and gotten this working and the main things that are needed are proxy-polyfill and the fetch-polyfill. The fetch-mock compatibility problems were [fixed]((JakeChampion/fetch#736) so IE 11 support should work out of the box. I've also created a repo that has the minimum changes needed for a CRA repo.
