Set max_term_width to 80

Closes #127

This required enabling wrap_help feature for clap.

Ah, you beat me to figuring that out. The clap docs took a little to read.

I don't think the max_term_width is needed. Once gdscript-formatter honors the terminal width (wrap_help), everything looks better.

I have a competing PR #129 that makes that change and then improves the help text (and makes the code more readable).

It will still be hard to read when the terminal takes whole screen's width. I think it is needed.

Ah, like a developer who has a terminal open at 300 columns? That makes sense.

How about setting it to 100 or 120, then? It gives the developer some choice but prevents insanity.

Though if a developer has a 300-column terminal, they are probably used to things being nigh unreadable.

What insanity? You wrote in the issue that 80 is the convention.

Thanks for the help as always! I bumped the number to 120 as it controls the max allowed text width, so it will still be 80 columns for someone who uses a small or split terminal view with 80 columns, and scale up to 120 for someone who wants a little more space. Hopefully that'll make terminal users happy.
