Percentage complete display rounding issue

[pR0Ps]

What version of this package are you using?
v0.21.0

What operating system, Node.js, and npm version?
macOS 10.14.6 (desktop application)

What happened?
The screenshot attached below shows a torrent at 99% downloaded. However, the completion percentage of each individual file has been rounded up to 100%. This makes it impossible to tell which of the file(s) is incomplete. In this specific case, I verified with another client that the torrent is 99.96% complete overall and one of the files is 99.71% complete.

What did you expect to happen?
I would expect that if a file is not fully complete, that it would not state "100%".

Possible solutions:

• Always round percentages down: Since percentages measure "completeness", it's generally not that bad if 0.99999% is displayed as 0% instead of 1%, as both clearly communicate "nowhere near done". It's a bit more critical that 99.99999% is clearly communicated to mean "not fully complete". This is already done for the total completion percentage.
• Special cases: If it's important to communicate the "has started" aspect of the 0.99999% case, special cases for 99% and 1% could be added (ie. show "1%" if >0% and <1%, show "99%" if >99% and <100%, otherwise round normally).

Personally, I'd also like if the percentages could be a bit more accurate (1 decimal place? 2?) but I understand that's more of a look-and-feel choice, not a bug (see #50)

Are you willing to submit a pull request to fix this bug?
Yes. I'll have a PR submitted in a few days that floors the percentage for the individual files before displaying them.

These changes sound great and I agree this should be fixed. Thank you for your attention to detail. Looking forward to your pull request.
