Description

Similar to ARROW-694, this is an umbrella issue for supporting reading JSON line-delimited files in Arrow.

I have a reference implementation at https://github.com/nevi-me/rust-dataframe/blob/io/json/src/io/json.rs where I'm building a Rust-based dataframe library using Arrow.

I'd like us to have feature parity with CPP at some point.
