    bytesInMemory estimates the size of IncrementalIndexRow key, it takes into account the timestamp(long), dims(Object Array) and dimensionDescsList(List). Each of these are calculated as follows:
    
    timestamp : Long.BYTES
    dims array : Integer.BYTES * array length + Long.BYTES (dims object) + dimsKeySize(passed via constructor)
    dimensionDescList : Long.BYTES (shared pointer)
    dimsKeySize : this value is passed in based on the key type (int, long, double, String etc.)
    Returns:
    
    long estimated bytesInMemory
