Add `simplifyFileSize` option

[KroshSputnik]

I added a new option to enable to show the files sizes in B, MB, GB, TB, PB.

Enable it in the options by doing 'simplifyFileSize':true

Not sure if I need to divide the size by 1024 or 1000. Also would I need to round the final size, as it seems the size returned for the file size is already rounded. Feedback will be appreciated.

Currently we support [email protected] so new ES6 syntax is not allowed:

Thanks for this proposal @KroshSputnik! Can you include tests and documentation?

Hi @UlisesGascon ~~I'm not sure how to add a test, do I need to create a new one in test.js?~~ ~~I have never created one before, could you walk it through?~~

I've added docs in readme and fixed the es6 issue.

Thanks

[KroshSputnik]

@UlisesGascon I have added test, for when the option is enabled and when it isnt.

Can you double check my pull request.

[bjohansebas]

It looks great, although we could probably delegate that logic to bytes instead of handling it ourselves.

@bjohansebas Updated the feature with your suggestion.

[bjohansebas]

Great! Once the tests are run, I'll be able to give my LGTM

[KroshSputnik]

@UlisesGascon All tasks completed. If need anything else, let me know.

[UlisesGascon]

mmm.. not sure why one of the new tests is failing :thinking:. Can you have a look @KroshSputnik ?

[KroshSputnik]

I think the issues due to the differences of how linux and windows calculate bytes.

I downgraded to node 0.8, but all tests pass successfully.
