 Patch contains
  * Optimised unzip_file() function
    * Reduced the number of IO operations required (mainly is_dir())
    * Simplifies logic to make reading easier.

 Also note, I played with extracting a file at a time from the ZIP, and
 writing  to the filesystem directly, While it decreased the memory usage
 from ~12MB to 3MB for  the entire unzip operation, It increased the
 operation time from 5s to 70s, So i've left it to consume memory in order
 to speed things up.
