public interface MacroSchemaMigrator
```
Performs macro schema migrations as part of the rendering pipeline.
A macro schema is defined as the definition of all the params and body type for a macro. If a macro's schema changes in an incompatible way, they should register a macro-schema-migrator to migrate from the given version in the macro-schema-migrator. Migrations will be performed in order as necessary.
