Version 0.4.0 New features: * Added the `extref` module, which encodes `&str` and `&[u8]` values as CBOR External Reference-tagged items rather than inlining them, as supported in OC-Wasm 1.12.2-0.5.0. Changes: * `computer::address` and `computer::tmpfs_address` now return `Address` instead of `Uuid`. * `computer::beep` now takes two `u16` values; `BeepParameter` no longer exists. * The CBOR-encoding of an `Address` now uses the Binary UUID tag instead of the Identifier tag, as supported in OC-Wasm 1.12.2-0.5.0. Dependencies: * Bumped `minicbor` to 0.19.
