Metaschema codegen binding parser

[nikitawootten-nist]

User Story:

As a Metaschema developer, I need my generated Metaschema classes to have the ability to save and load XML, JSON, and YAML.

Goals:

• An approach for the bound XML, JSON, and YAML parsing is chosen and documented as an ADR entry
• Implementation for bound classes for the relevant object models
• Creation of the binding parser capable of (de)serializing bound classes
• Adjustment to the generated classes of Metaschema codegen #14 to use the binding decorators

Dependencies:

The code generation for the basic classes must be complete: #14
