Add option to trim floating points from CPU percentage

[h0adp0re]

I have a relatively simple request, I'd like an option to trim floating points from CPU percentage as they add no value to me and make the percentage harder to read at times.

This would be great, as the CPU output would be similar to the MEM output which doesn't seem to have floating points.

Oh yeah, that's a good point. There are some inconsistencies:

• The metric for used CPU percentage, #{cpu.pused}, has floating points.
• The metric I'm using for RAM, #{mem.used}, has floating points, as it should, since it's in gigabytes.
• The metric for used RAM percentage, #{mem.pused}, does not have floating points.

It'd be nice to have some consistency, in addition to visual grepability. Or maybe it would be easier to remove floating points entirely from metrics displayed as percentages?

You may wanna take a look at #8 (comment).

Thanks for putting time into this! Alas, I've resorted to using https://github.com/tmux-plugins/tmux-cpu since. It has all I need and it's under the official organization, which is a small pseudo-guarantee.
