To properly support more than 2Gi input we have to support being asked to resize more than once. Previously we would only have to resize the one time because we went from our 4K stack buffer to the final size heap buffer. But now, since our input size can only be specified in int, we have to deal with looping over the input and resizing the buffer as needed. We also have to deal with trailing data at the end of our sliding window potentially causing issues for the encoding. So we try to shrink our window when it causes issues, or store the trailing data for the next call. The >2Gi test takes about 6-8 seconds on my machine.
