Non-compressed GZIP file is not property handled

[kasimok]

Hi, @PaulTaykalo Recently, I found the xadmaster/The Unarchiver cannot deflate particular GZIP files. However, the other Apps such as Keka can, please take a look at this file(please unzip it first). CINEMAENTUCASA_v5.apk 2.cpgz.zip The file signature is 1F 8B 08 00; unlike most other gzip files, the 4th byte of the file is "0x00". So I guess maybe there are some bugs in the XADGzipParser
