Version 0.12.0

New features:
* Added new `computer` module syscall `free_ram` from OC-Wasm version
  1.12-1.0.0.

Changes:
* OC-Wasm-related crates will be versioned in lockstep, starting from
  0.12.0. This means that equal version numbers should now be compatible
  with each other.

Maintenance:
* Bumped `minicbor` dependency to version 0.21.
* Bumped `ordered-float` dependency to version 4.
* Bumped `oc-wasm-sys` dependency to version 0.12.

Version 0.5.0

Dependencies:
* Bumped `minicbor` to 0.20.

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.
