The encodePacked function takes two arguments: types and values. It returns a hex-encoded packed data.
types is an array of PackedAbiType objects, which define the ABI types to be packed encoded. The PackedAbiType objects are created using the abi.PackedAbiType constructor.
values is an array of primitive values that correspond to the ABI types defined in types. The values are passed as arguments to the function and are used to populate the packed data.
The function uses the abi.pack method to pack the data into a hex-encoded string. The resulting packed data is then returned as a hex string.
The function is useful for generating packed data that can be used in solidity contracts. It allows developers to create packed data that conforms to the ABI standards and can be easily integrated into their contracts.

In this example, the types array defines three ABI types: address, string, and bytes16[]. The values array contains the corresponding primitive values that will be packed into the packed data. The resulting packed data is a hex-encoded string that can be used in a solidity contract.
