JS client for DatoCMS REST Content Management API

/**
 * DatoCMS Block Field Value Processing Utilities
 *
 * This utility provides a unified interface for working with blocks embedded within DatoCMS field values.
 * DatoCMS supports three field types that can contain blocks:
 * - Modular Content fields: arrays of blocks
 * - Single Block fields: a single block
 * - Structured Text fields: complex document structures with embedded blocks
 *
 * The challenge this solves: Each field type stores blocks differently and requires different
 * traversal logic, making it complex to perform operations like transformations, filtering,
 * or searching across blocks regardless of their containing field type.
 *
 * This utility abstracts away these differences, providing a consistent API to:
 * - Visit/iterate through all blocks in any field type
 * - Transform blocks while preserving field structure
 * - Filter blocks based on conditions
 * - Search for specific blocks
 * - Perform functional operations (map, reduce, some, every)
 *
 * All functions come in both sync and async variants to support different use cases,
 * particularly useful when block transformations require async operations like API calls.
