SLTev fails to delete temporary directory and reports mwerSegmenter failure

[bhaddow]

Hi

When I run SLTev, it fails, reporting that mwerSegmenter is missing. After some digging, I realised that mwerSegmenter is fine. The problem occurs at this line:

SLTev/SLTev/files_modules.py

Line 214 in 2d56dd0

shutil.rmtree(temp_folder_name)

The directory deletion fails (not sure why, could be an nfs problem) an exception is thrown, caught and turned into a mwerSegmenter error. Setting ignore_errors=True in shutil.rmtree(temp_folder) is a temporary fix, but I think the real fix is to use python's tempfile module to create a temporary directory.

A further problem is that catching the error, and outputting a generic mwerSegmenter message, makes this harder to debug
