Python3: TypeError: a bytes-like object is required, not 'str' #3

The traceback points to vast.py line 405. It looks like this is because the file is being opened in binary mode, and Python3 is strict about using binary data for files that are opened as binary.

The README lists this project as only using Python 2.7.

Updating to 3 is definitely something we should do, but at the moment there is no official support for 3.

The "fix" would be removing the b flag from the file open operation, but as you mentioned in-person, that would probably break on any unicode content that would need to be written to the file. I'm closing this issue since a migration to Python3 would be a larger undertaking than this one issue.
