Currently when an instruction creator is called, it hardcodes the programAddress part of the program to the program that the client is being rendered for. This PR adds a new optional config parameter to instruction creators, which can be used to override the programAddress. For example:

import {
    getTransferCheckedInstruction,
} from '@solana-program/token';

const sendTokenInstruction = getTransferCheckedInstruction({
    source,
    destination,
    amount,
    authority,
   decimals,
   mint,
  }, { programAddress: TOKEN_22_PROGRAM_ADDRESS }
);

This is useful when there are multiple programs with compatible instructions, for example in the case of token and token22. In these cases, when dealing with these compatible instructions, you can now re-use the token client and just change the programAddress of the generated instructions.
