 * - **index**: the array index of the instruction within the transaction
 * - **iso**: the isolated size of the instruction (marginal cost of only the instruction)
 * - **mar**: the marginal size cost of the instruction (when added to previous)
 * - **cum**: the cumulative size of the instructions up until that instruction
 * - **quota/used/left**: [BPF instruction compute unit info](https://docs.solana.com/developing/programming-model/runtime)
 * - **CPI**: [the maximum depth of CPI](https://docs.solana.com/developing/programming-model/calling-between-programs) (current limit in Solana is 4)
