Fix crash by avoiding hardcoded index for moduleHash

The previous implementation attempted to retrieve `moduleHash` from the `softwareEnforced` sequence using a hardcoded index (index 2).

However, fields in the Key Attestation `AuthorizationList` are optional. In observed crashes, index 2 actually corresponded to `keySize` (Tag 3, ASN1Integer) rather than `moduleHash`, causing an `IllegalArgumentException` when the code attempted to parse it as an `ASN1OctetString`.

This commit replaces the index-based access with a dynamic lookup for Tag 724.
