Generate documentation

Probably could use https://typedoc.org/.

Needs https://github.com/rustwasm/wasm-bindgen/pull/2450, which will come with the next release.

Should be a lot faster: https://docs.rs/arrow2/0.1.0/arrow2/.

I think https://developer.mozilla.org/en-US/docs/Web/API/ReadableStreamBYOBReader can help us reduce memory copies. It only works in Chrome right now, though.

Add support for - [ ] date - [ ] dictionary encoded - [ ] list and struct vectors - [x] string vectors

Reference types

Check whether https://rustwasm.github.io/docs/wasm-bindgen/reference/reference-types.html helps with performance.

CSV and JSON reader

Support reading CSV files into a table. We currently only support IPC.
