FetchAlgoAddressesFromPackedValue returns all non-zero Algorand 32-byte PKs encoded in a value (up to 3).

FetchBToIFromState fetches a specific key from application state - stored as big-endian 64-bit value Returns value,and whether it w found or not.

FetchUInt64sFromPackedValue returns all non-zero 64-bit ints contained in the slice (up to 15 for a single local-state fetch for example).

FetchUint64sFromState fetches a specific key from application state - stored as set of 64-bit values (up to 15) // Returns array of values, and optional error.

MergeNFDProperties - take a set of 'split' values spread across multiple keys like address_00, address_01 and merge into single address value, combining the values into single 'address'.

RawPKAsAddress is simplified version of types.EncodeAddress and that returns Address type, not string verison.
