refactor: use options object for WASM function args, improve docs

- Add relevant links to all READMEs and source code
- Resolve clippy lints

czv:

- Add more docs for top-level items
- Add suggestion to use builder methods instead of functions
- Disable slice and slice tests until operation is complete

czv-wasm:

- Use tsify_next for allowing objects as parameters
- Add nodejs example and instructions
