MultiPart, file, got error "TypeError: sequence item 0: expected a bytes-like object, str found"

Hi there.
Are you testing file proxying?

I'm faced with this error.
I'm little diving in the problem, and found this place:
rest_framework_proxy/utils.py:61

return b'\r\n'.join(output)

Maybe I don't understand something, but output contains strings => we got this error.

P.S. Also, there is something strange with package releases. In pypi actual version 1.6, but in this repo I see 1.4 as latest.

Hi, I can confirm this error happening on Python 3.7 and DRF proxy 1.6 as you are trying to join string mode list with bytes. Should be encoded like in #26.
