Issue

smithy-lang/smithy-typescript#1221

Description

Prototyping serde alternative that accepts a Smithy json model at runtime.

Goals:

• performance and code size parity or improvement vs. current code gen serde
• allow runtime provision of models such as a regular Smithy JSON model file or compressed form
