pngquant is not thread-safe #1

Compress multiple images in threads. They overwrite each other.

Ran into the same issue. Workaround seems to be to use a different tmp_file for each thread. e.g.: 

pngquant.config(tmp_file='unique_filename')

Change to generate tmp file random https://github.com/Brightcells/pngquant/commit/6ed0525056a5ce943bb3826cd29bc09f0edcae12
