Word wrap is lost when Yargs is used as ES module

[jwbth]

Wrapping breaks words at Nth character when Yargs is used as an ES module. As soon as I switch to CommonJS, word wrap is back to normal. That's basically all.

Yargs v17.3.1, Node v14.17.0, Windows 10.

Found a similar issue #1938, it turned out to be a problem of esbuild. It is not used in my case.

@jwbth this was a decision made when migrating to ESM, as the library we used for wordwrap was not yet ported to ESM, I believe we could now go back to using a library that works as expected for ES modules.

Edit: one problem, is I do think the word wrap deps we relied on no longer support CJS 🤔 , perhaps we should consider switching behavior in yargs 18, such that word wrap works as expected for ESM, but not CJS.

Edit 2: I believe the culprit is string-width.

Any updates on this? I'm getting this behaviour too. (yargs 17.5.1)
