data: a string (values between 0 and 255) that contains packed unsigned integer numbers
startUIntIndex: the zero-based index from which on data should be unpacked (from data[4*startUIntIndex+1+additionalCharOffset]). Can be omitted in which case 0 is used
uIntCount: the amount of uints that should be unpacked. Can be omitted in which case 0 is used (which indicates that the maximum of uints should be unpacked from the indicated startUIntIndex)
additionalCharOffset: a char offset that will be added before reading the uints. Can be omitted, in which case 0 is used.
