Replace class-transformer

We need:

• Custom transformation (Date => date only json representation, using custom tranformation function, etc.)
• Property rename
• Exclude properties from serialization

[gius]

Transformation is supported:

• https://docs.deepkit.io/english/serialization.html
• https://github.com/deepkit/deepkit-framework/blob/1c9094844821d9eb049332a83c69e80347f5472a/packages/type/tests/transform.spec.ts
• https://github.com/deepkit/deepkit-framework/blob/1c9094844821d9eb049332a83c69e80347f5472a/packages/type/src/field-decorator.ts#L125-L162

Rename should be handled after serialization / before deserialization:
marcj/deepkit#21

Exclude is supported:
https://github.com/deepkit/deepkit-framework/blob/master/packages/benchmark/src/type/serialization/medium-deepkit.bench.ts#L47

External schema definition:
marcj/deepkit#51

We could also use Zod and then apply mobx's autoObservable.
