Given an SPL Token Mint key and associated fee account (the fee account the instruction passed in) validate that the fee_account is correct for the fee mint. If the account is not initialized then call the create instruction.

1. Get the derived associated token address
2. Check that the address is the same as what was passed in and the owner is correct
3. Check if the token address is initialized
4. If not initialized, call cross program invocation to create_associated_token_account to initialize
