/**
 * Creates a subdomain for the specified domain. This includes setting up the subdomain

 *
 * @param params - An object containing the following properties:
 *   - `rpc`: An RPC interface implementing GetAccountInfoApi and GetMinimumBalanceForRentExemptionApi.
 *   - `subdomain`: The subdomain to create, with or without .sol (e.g., something.sns.sol or something.sns).
 *   - `owner`: The address of the owner of the parent domain.

 * @returns A promise that resolves to an array of instructions required to create the subdomain
 *   and its reverse lookup record.
