Refactor to improve states

*   Remove custom kind wrappers, use plain bytes instead
*   Remove `Into`s, use the explicit expected types instead
*   Refactor to use `slice.as_str` in most places
*   Remove unneeded unique check before adding a definition
*   Use a shared CDATA prefix in constants
*   Inline byte checks into matches
*   Pass bytes back from parser instead of whole parse state
*   Refactor to work more often on bytes
*   Rename custom `size` to `len`
