ansi_strwrap() needs a better implementation, that does not rely on base::strwrap()

If an hyperlink has spaces, should it be kept together?

for example

"here is {.href [I am a very longggggggggggggggggggg link to a website](https://github.com)

Should it be all kept on the same line?

@olivroy I don't think so.

But that's not really what this issues is about. base::strwrap() is simply slow, and it is really tricky to rely on it while keeping the ANSI sequences.
