Generate deserializers dynamically for nested types

[rcoh]

Description of changes:

This code replaces the hand-written deserializers that were used to serialize types like Instant & Blob with autogenerated code. A follow-on diff will do the same thing for serializers.

Supporting this required refactoring blob serialization to use the newtype serializer pattern

Once sufficiently developed (and if desired) this would allow us to completely remove our use of Serde-derived serializers with serializers & deserializers generated at codegen time.

Generated code diff: main-generated...generate-deserializers-generated

you need this println for something?

It prints a link to the generated file I can click in the intellij terminal
