feat: Support native inference parser for dataclass-like annotations.

[DanCardin]

This is probably blocked on #117. Realistically, the current annotation and extra_annotations used by the parsers is bad DX in comparison to something like TypeView. If all the parsers are going to end up refactored to be defined in terms of single-level value/annotation, it's going to make a lot more sense when the actual annotation bit is a TypeView instead.

Result based of discussion from #137

The main problem with automatic dataclass-like inference, is that we can't know, without the annotation and an explicit decision from the user, whether a list[T] input is the appropriate input for the class itself, or if it wants the inputs to be splatted into the constructor.

For anything where the single value would make sense today, it should already work.

---

As implemented, this is perhaps a decent amount more complicated because it's using the invoke machinery to apply all parse operations now. It's not necessarily a problem, it's just a decent amount more code being evaluated for every parameter to introspect the function's parameter annotations before calling the function, versus just calling the function.

It's now moderately more complicated at the collection phase, but not overly so, and the actual parse step is no more complicated. And compose can be handled with lists of parsers, which is the biggest simplification.
