A collection of tools for working with neon-bindings to interop between node and Rust.

• Serialize to/from special types like Duration, U256, Vec<u8> (from a hex string or ArrayBuffer), RecoverableSignature, etc.
• More safely deal with the Throw hazard presented by the neon-bindings error model avoiding segfaults and recovered errors re-throwing
• Threadsafe Proxy types to easily access Rust data owned by a JavaScript instance
• run_async to schedule work on microthreads
