Fit float/int representation for progress bar

[astrofrog]

For iterables with sizes that don't require suffixes in the progress bar, it might make more sense to use integers:

In [2]: from astropy.utils.console import ProgressBar

In [3]: ProgressBar([1,2,3]) 
|>------------------------------------------| 0.0 /3.0  (  0.00%)

Tagging as low-priority and easy in case a GSoC student or other first time contributor wants to give it a try.

I would like to try to work on this.
Please check if I understand the issue correctly: the 0.0 /3.0 part in the progress bar should be changed to 0 /3.

@CNA-Bld - @orangeblock has already filed a pull request for this (#2202)

@astrofrog Ooops I was using mobile phone and never noticed that... Thank you anyway!

@astrofrog: I think #2202 is unrelated. It has to do with the display of file sizes. The bug report here has to do with percentage completion.

[astrofrog]

@mdboom - actually I meant for the issue here to not be to do with the percentage (which is fine as-is) but my problem above was the 1.0 / 3.0 which I thought is what was fixed in #2202?

[mdboom]

@astrofrog: Indeed. You are right.

Fixed in #3299 .
