Implementation of the libp2p Transport trait for external transports.

This Transport is used in the context of WASM to allow delegating the transport mechanism to the code that uses rust-libp2p, as opposed to inside of rust-libp2p itself.

Note: This only allows transports that produce a raw stream with the remote. You couldn't, for example, pass an implementation QUIC.

Usage

Call new() with a JavaScript object that implements the interface described in the ffi module.
