Add JSON Schema -> C++ streaming parser generator

Browse Source

Generates a C++ type and a streaming builder parser from a JSON Schema,
built on weaseljson. The builder copies incoming bytes directly into their
final destinations in the result struct (no intermediate DOM) and hands
back ownership via take() once parsing completes.

Supports objects/structs, required vs optional (std::optional) fields,
nullable types, string enums, arrays, $ref including recursion (broken
with unique_ptr), and additionalProperties (strict reject or skip).
Unsupported schema constructs are rejected at generation time; schema
violations are rejected at parse time.
