TokenFeeScheduleUpdate

At consensus, updates a token type’s fee schedule to the given list of custom fees. If the target token type has no fee_schedule_key, resolves to TOKEN_HAS_NO_FEE_SCHEDULE_KEY. **** Otherwise, this transaction must be signed to the fee_schedule_key, or the transaction will resolve to INVALID_SIGNATURE. If the custom_fees list is empty, clears the fee schedule or resolves to CUSTOM_SCHEDULE_ALREADY_HAS_NO_FEES if the fee schedule was already empty.
