Undo changes from following commit:
83964ebc5e
Change the open mode for the output file from 'wb' to 'w' so the
output file is written as a text file and not a binary file.
This resolves the issue where the text file was not writable from
Python 3.x and also removes b'' from output file when the string
was encoded as a bytearray.
