Before, the Wrapper would be generic in the type of WordSplitter used. This meant that Wrapper<NoHyphenation> would be a different type than Wrapper<HyphenSplitter>. The result is that you need to fix the type of WordSplitter at compile time. This makes it hard to make interactive programs, something which was raised in #178. Making splitter a Box<dyn WordSplitter> makes the field less special. We can therefore simplify the API by removing the with_splitter constructor. The performance is unchanged by this, even when testing with the hyphenation feature enabled.

This commit reverts the internal changes of mgeisler#206, but keeps the public API compatible to what it introduced. Essetially by adding a default for the type parameter. However, now in addition to the dynamic dispatch by default, one may also explicitly use static dispatch by specifying the type parameter. This now allows to construct an `Options` instance in const/static context. Which is further facilitated by adding the const fns `new_const` and `with_splitter`. This change is actually backwards compatible with the previous commit, as seen by the unchanged examples and tests.

Also, since `Options` now may be some specific type the `Clone` derive is added again. So when `S` is `Clone` then `Options` is `Clone` too. This change is actually backwards compatible with the previous commit, as seen by the unchanged examples and tests.
