Update package.json's main prop

It looks like this package does not work on Node < 10 because of the for...await feature:

 /home/lion/Code/aragon/aragon-cli/packages/aragon-cli/node_modules/ipfs-http-client/src/files-regular/index.js:60
      for await (const entry of get(path, options)) {
          ^^^^^

I think the issue here is that main points to src instead of dist.

We don't do any transpilation on the CDN version either. The engines field in the package.json is wrong and we need to update it to the version of Node.js that supports for await, which is 10.3.0.

@0x6431346e would you be up for sending a PR?

Fair enough, what's the point of the dist folder and the build script though? (curious)

It is for use in the browser with a script tag.
