this package does not work any more in python3.8+

[braindevices]

with tee.StdoutTee('/tmp/testtee.log'):
...     sys.stdout.write('hello\n')
self.fp = open(self.filename, self.mode, self.buff)
ValueError: can't have unbuffered text I/O

we need to set buff=1 at least to make it work.

I have the same issue and buff=1 like tee.StdoutTee('foo', buff=1) solved my issue too.
