Replace forked cliui with original version

[nrayburn-tech]

Fixes #20.

There's a regression when updating to string-width 7.2.0. I'm going to review and possibly create an issue in that repo. This should probably wait until it's resolved, but I wanted to go ahead and create this PR to see if there's any interest in making this change back to the original cliui library.

The regression seems to come from checks added in string-width 7.2.0 to handle zero-width strings differently. I'm not entirely sure if it's a bug in that library as it looks like that change was made pretty intentionally.

Failures are specifically related to when codePoint is 0x20_0B, the zero width space.

Pretty sure that https://github.com/isaacs/jackspeak/blob/main/src/index.ts#L1339-L1388 is where the problem is. I'm not very familiar with the code here, so if somebody else has a solution then feel free to create a separate PR with the relevant changes (or push directly to this branch if you have access). Otherwise, I'll look into a resolution when I have time.
