calculate file downloaded correctly

[jimmywarting]

I notice file.download is calculated wrong.

Using the Sintel torrent as an example...
https://instant.io/#08ada5a7a6183aae1e09d831df6748d566095a10
(this can be tested in the console)

It has 6 srt files and 1 small piece of the mp4 file in the first piece
after the first piece is downloaded you can see that the first files are complete but the progress and downloaded are incorrect

const file = client.get('08ada5a7a6183aae1e09d831df6748d566095a10').files[0]
console.log(file.done) // true
console.log(file.progress) // 39.58777239709443 <- incorrect b/c of download
console.log(file.downloaded) // 65399 <- this file fits inside one chunk and it's too big
console.log(file.length) // 1652

Could you maybe add a test where it fails with current code and works with your PR?

Done

I'm glad you could figure the tests out
