}
Writes a heap into the object's own SQLite.

Elides, chunks, then inserts each chunk as a bound BLOB parameter (base64 would become statement text and blow DO_SQLITE_MAX_STATEMENT_CHARS). The fd table is stored with the bytes it belongs to, never rebuilt from another instance.
Parameters
- sql: HeapSql
- opts: {
      chunkBytes?: number;
      generation: string;
      handles?: HandleRecord[];
      heap: Uint8Array;
      nowMs: number;
      pageBytes?: number;
      streams: StreamRecord[];
  }
Returns {
    compressedBytes: number;
    digest: string;
    id: number;
    keptPages: number;
    root: string;
    rows: number;
    storedBytes: number;
}
- compressedBytes: number
- digest: string
- id: number
- keptPages: number
- root: string
  
  the integrity root of what was written, for the caller to seal outside SQL
