SimulateArray.huff

/** 
 *  SUM_ARRAY HUFF EXERCISE
 *
 * In this puzzle, the task is to simulate an array in Huff using the "exact" storage pattern as solidity. Expected functions can; 
 *      - Push numbers onto a array, 
 *      - Pop the last index from the array,
 *      - View what's stored at an index, 
 *      - Gets the length of the array, 
 *      - Write to an index if it is valid.
 *
 *      - Writes and reads outside of length revert. 
 *      - Popping off a zero length array reverts.
 *
 *  NOTICE: The contract should revert when an unrecognized function is called
