Thank for the tip! By using the `DataExtractor::ExtractBytes` method instead of
my boiler-plate, I was able to simplify the code.
However, I had to remove the asserts from the `DataExtractor::ExtractBytes`
method.
I am not sure why they were inserted.
I think that the method is able to handle inputs of arbitrary length.
