wip: example with deno

[oliveriosousa]

This PR is a WIP example of running IPFS using Deno.

Since js-ipfs uses CommonJS and Deno uses ESModule it is possible to have some compatibility with Node.JS but not every builtin is implemented and some are partly.

The std/node library

The std/node part of the Deno standard library is a Node.js compatibility layer. It's primary focus is providing "polyfills" for Node.js's built-in modules. It also provides a mechanism for loading CommonJS modules into Deno.

The library is most useful when trying to use your own or private code that was written for Node.js. If you are trying to consume public npm packages, you are likely to get a better result using a CDN.

Copied from Deno

When using this method, it throws the following error:

Alternative

It is possible to also use JSPM which will convert NPM modules to ES Modules

When using this method, it throws the following error:
