v0.3.0 Release (#3) - Zero Copy

Most of the API is exactly the same, as is usage, with the exception of a few things:

* `Request` has been renamed `Prompt` because in actual use this makes things clearer.
* Almost everything supports zero-copy deserialization where possible at the possible cost of cognitive overhead, however most code will require no changes. Cow strings are used everywhere. This also allows static `Message`s and the like to be created at compile time.
* `Stream` is now `Send`.
* Added an example of an Assistant using Python to solve problems.
* More convenience methods like `to_static` for some structs.
* A few bug fixes
