ipfs@0.41 update: option 1

[zebateira]

First option for dealing with the new js ipfs api that always returns iterables.
This first approach adds a for await...of loop.

• Still working out how to solve the linting warnings on the monaco editor
• Although it looks a bit convoluted, it might be a better choice if we don't want to introduce a module when teaching

See original WIP PR: #381

Alternatively, we could also take the ipfs.add operation out of the for loop:

Initial code:

/* global ipfs */
const run = async (files) => {
  const result = []
  const operation = // Place your code to add a file or files here

  for await (const resultPart of operation) {
    result.push(resultPart)
  }

  return result
}
return run

Solution code:

/* global ipfs */
const run = async (files) => {
  const result = []
  const operation = ipfs.add(files)

  for await (const resultPart of operation) {
    result.push(resultPart)
  }

  return result
}
return run
