BUG: Tests Dumping PNG Contents To Stdout

TIA Toolbox version: 1.0.0 (develop)
Python version: 3.9
Operating System: Travis CI

Description

A test in test_stainaugment is causing a whole PNG file to be dumped to stdout. Here is some sample output from Travis:

Update: It appears in different places on different runs and is likely not to do with stain augmentation but rather some other thread or process dumping to stdout during tests running.

tests/test_stainaugment.py Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/%{ <-- HERE (.*?)}/ at /usr/bin/run-mailcap line 528.

Error: no "view" rule for type "image/png" passed its test case

       (for more information, add "--debug=1" on the command line)
