/**
 * Mapping strategy for tag 49 - Acquirer Network Identifier.
 *
 * Tag 49 contains:
 * - Subtag 00: GUI (Globally Unique Identifier, e.g., CO.COM.CRB.RED)
 * - Subtag 01: Short code (e.g., CRB)
 *
 * This strategy resolves and maps the subtags, and adds a human-readable network name.
 *
 * Example output:
 * ```ts
 * {
 *   gui: "CO.COM.CRB.RED",
 *   networkId: "CRB",
 *   networkName: "Credibanco"
 * }
 * ```
 *
 * @param tlv - TLV entity for tag 49
 * @returns An object with `gui`, `networkId`, and resolved `networkName`
