Echo JS 0.11.0

Hello,  
I know I have already shared this project here but it is now much more advanced than when I first introduced it.  
The main new features are the ability to have a Deno specific implementation for some files ( `foo.ts` for NPM and `foo.deno.ts` for Deno ) and the ability to control how the import statements are replaced.

Disclaimer: Although EVT is a marked improvement over EventEmitter it can't compete in teme of feature scope with RxJS yet.
There are important operators such as swichMap, mergeMap, debounceTime and others that do not have an equivalent in EVT.
However, EVT has two main things going for it already:
It allows performing filter, map and scan in a single operation which makes the code much less verbose and enables typescript to seamlessly infer what is going on.
It is more accessible, the API is close to EventEmitter which allows getting started quickly and progressively leverage the more advanced features.
Any feedback much appreciated

And for the NPM modules authors that are interested in supporting both Deno and Node with a single codebase like EVT does, checkout https://github.com/garronej/denoify

Not yet, but I think there are some good ideas in it.
