Temporarily removed the pre_gamma release for Linux

I had to temporarily remove the pre_gamma release for linux, I forgot to make a few necessary changes in the hsz.py and unhsz.py files, which I only realized that I had left out when I tried to run hsz on Arch Linux, after the install, and received an error message saying that hsz couldn't find info.so. As soon as I get everything set I'll reupload the pre_gamma release and everything'll be back to normal.

Sorry about the inconveniences this may cause/caused.
