Batson

[samuelcolvin]

Adding "batson" binary alternative to JSON code crate.

From the README:

Binary Alternative To (J)SON. Designed to be very fast to query.

Inspired by Postgres' JSONB type and Snowflake's VARIANT type.

For a relatively small JSON document (3KB), batson is 14 to 126x faster than Jiter, and 106 to 588x faster than Serde.
