Add wordWrap function

Reference implementation: https://github.com/jonschlinkert/word-wrap

I like the idea, and I think the functionality would be a good addition here. However, I see two points that might argue against it:

1. The original implementation is around 60 lines long and seems relatively complex, which could contradict one of Radashi's principles of Concise Implementations.
2. Even though the other library hasn't been updated for a year, it still seems quite stable. At the moment, I don't see much value in creating our own copy, as the open PRs and issues don't seem particularly relevant.

1. I don't think we would support every edge case or option that word-wrap does.
2. One of the goals of Radashi is to reduce the number of dependencies (and therefore risk of supply chain attacks), so the fact that a function already exists in another package is not a real concern. The discussion in Add LRU cache #189 is also relevant here, I think. Our design ethos will naturally lead to a concretely different approach, most of the time.

The biggest concern I have with adding a wordWrap function is whether it's actually a popular enough use case. We should probably wait on this one until more demand is clear.

Drive by comment: the reference implementation you linked to in the OP is not a robust implementation. To do it robustly, you need to account for surrogates and grapheme clusters, which would likely require a more complex implementation and potentially additional deps. The cut option and its behavior is also too naive. For justified text, using TeX's algorithm would be better.
