Codec<S, T> class abstract mixin

A Codec encodes and (if supported) decodes data.

Codecs can be fused. For example fusing json and utf8 produces an encoder that can convert Json objects directly to bytes, or can decode bytes directly to json objects.

Fused codecs generally attempt to optimize the operations and can be faster than executing each step of an encoding separately.

The Codec class provides a default implementation of encode, decode, fuse and inverted. Subclasses can choose to provide more efficient implementations of these.
