Overview

builder class facilitates the hash_check and building process by monitoring if all parts of a file have been requested, if not when a higher index part is requested all the other previous parts will be sent along as well, this is necessary for cases where a file doesn’t have as many internal parts or none at all. This way the hash and all the parts of the file will still be there if layout has two parts and only last part -1 is requested, this builder will give back part 0 and part 1 if layout would have had three parts then it would have given back all three. if a part does not exist then it will come back as empty string, same for an index out of bounds
