Support Links with parenthesis

[Richard-Gist]

PROBLEM

Ink does not currently parse URLs with parenthesis () correctly, because it reads until the first closing parenthesis ).

Example

Wikipedia has numerous links like this.
Github parsing: markdown example
Raw markdown: [markdown example](https://en.wikipedia.org/wiki/Service_(systems_architecture))

SOLUTION

Use a balancing approach and count how many new opening parenthesis ( appear to ensure that reading continues until the final closing parenthesis is encountered.

Other solutions

I saw that there was already a PR that was a couple years old by nickd that hadn't been merged. It took the approach of counting opening parenthesis after reading ended, then continue reading until the final parenthesis is closed (accounting for new opening parenthesis).

I tried my tests on both solutions, and they both pass. I also ran some performance tests and they are essentially equal (0.0000X difference) in that regard.

If that solution is merged instead, I'm happy to close this PR.

Feel free to make any changes you want to the PR.

I believe the failure in Ink-Linux is unrelated to my change.

I'm not sure how to update bitrise to fix the issue in Ink-Linux, but it appears to need a newer version libcurl.

This looks like a useful contribution from @Richard-Gist.

@JohnSundell Any chance of these open PRs getting a little love, please?

@Richard-Gist I'm so sorry for taking so ridiculously long to review this PR. It's an excellent addition to the library, and I think you solved the problem in a very elegant way. I also appreciate how you included context, such as performance testing (which is super important for Ink), in your PR description. I'll sort out the CI issues, and will get this merged once that's done. Thanks a lot for contributing!
