feat: ES Module prototype

[iamnewton]

The concept here is to showcase that browser support for ES modules is widespread and will work as a mechanism for exposing the functions that come from bidding_logic_url and decision_logic_url.

This shows ES modules working locally and presumably in production, but from the same domain. Here's a cross-domain example.

Fixes: #13

[iamnewton]

we can optimize performance by preloading the module. This is a new directive that has relatively good support.

[brodrigu]

should we test injecting this tag using JS to make sure dynamic loading will work?

[brodrigu]

Looks like this should work. good stuff.

[iamnewton]

@brodrigu added in a new example to showcase a basic unrealistic example of the auction; can you look again?

[brodrigu]

simple auction function looks good, I still think we need to explore dynamically including a module and possible multiple modules exposing the same function names just for clarity (though I suspect it will work).

I still think we need to explore dynamically including a module […]

Create an issue and we can create a new demo for this. I think the point of this prototype was to create a simple example to prove out that it works. We can certainly create more variations to prove out more.

possible multiple modules exposing the same function names just for clarity (though I suspect it will work).

This sounds like another issue we can create.

If you think we should add more to this prototype, then let's create the issues still and assign/link them to this PR. But if not, can you approve and merge this PR and we should still create the issue and open a new PR that adds that functionality?
