RuntimeWarning: line buffering (buffering=1) isn't supported in binary mode

[mgalardini]

Hi, thanks for the great library. When doing the following operation in python 3.8, a runtime warning is raised:

>>> import pybedtools
>>> import tempfile
>>> tmp_bed = tempfile.NamedTemporaryFile()
>>> test = pybedtools.BedTool(tmp_bed.name)
>>> test.sort()
/home/mgalactus/minimamba/envs/pyseer/lib/python3.8/subprocess.py:849: RuntimeWarning: line buffering (buffering=1) isn't supported in binary mode, the default buffer size will be used
  self.stderr = io.open(errread, 'rb', bufsize)

I found this thread with some more details on why this warning is now raised. This seems the line where the warning is raised.

@mgalardini this should be fixed as of #324 -- hope to have a release sometime soon.

Also seeing this warning. Glad that it has been fixed, but when will there be a new release?
