Allow overflow

[Brod8362]

Allows values to go over maximum with the flag -f, --allow-overflow. This will cause the bar to wrap around and display in a color defined by --overflow-color (default is red, #FFFF0000).

Mentioned in issues #22 and #54.

Normal operation:

Overflow (with color set to green):

The archlinux and freebsd tests are failing, doesn't seem to be related to the code though.

Maybe instead of trying to display what's above the overflow you can just fill the bar 100% and set color to overflow-color. Or at least have this as an option?

[Brod8362]

Added that as --no-wrap. The default behavior is to wrap around, and if --no-wrap is set it will simply display at 100% in the color specified by --overflow-color

Cool!

I'm daily driving this PR, it works very well and is very handy for pulseaudio volume feedback 👍

Thank you for this MR. I have fixed the Archlinux CI - should be passing now after rebase.

Also please squash commits into single one.

Also please squash commits into single one.

Maybe you already know this and have a reason not to, but just wanted to mention that you can squash the commits yourself when merging (see github docs, step 3).

[Brod8362]

Everything finished.
The formatter appears to have taken some... creative liberties around line 557 in main.c.

I can squash the commits if you want me to, but it would probably be tidier to squash it yourself when merging as per @nichobi's comment.

Any updates on this?

Sorry for the delay, I've been busy lately 🙁
