Blueprints parser, mapper, and validator autogenerated from JSON Schema (#23)

Solves the Blueprint parsing problem as follows:

* JSON Schema is the source of truth for the Blueprint data structure
* Model classes are generated from JSON Schema
* Input Validation is done against the JSON Schema
* Mapping validated input into model instances is indirectly done based on the JSON Schema

## Summary of the approach

We use [Janephp](https://github.com/janephp/janephp/) to infer the PHP model class structure from the JSON schema

We then use Jane's output to generate PHP code using [Nette PHP generator](https://github.com/nette/php-generator):

* Model classes
* Interfaces for groups of related classes: `StepDefinitionInterface`, `ResourceDefinitionInterface`.
* Interface resolution map for the [JsonMapper library](https://jsonmapper.net/).
* PHP docstrings with more accurate types than Jane to guide the mapping process

From there, the data pipeline looks as follows:

1. Parse raw JSON
2. Validate it with Opis
3. Map it into PHP models using JsonMapper

Or, if you're consuming the PHP API directly:

1. Create Model instances
2. Validate them with Opis

## Rationale

Parsing and mapping JSON [in TypeScript is a simple problem, but in PHP it's surprisingly involved](WordPress/blueprints#13 (comment)). This PR combines three previously explored approaches into a single pipeline:

* WordPress/blueprints#17
* WordPress/blueprints#19
* WordPress/blueprints#21
