The included patch makes type checking of the arguments of StringIO
consistent between pyio and io.

>>> import io
>>> io.StringIO(b"hello")
Traceback (most recent call last):
  ...
ValueError: initial_value must be str or None, not bytes
>>> io.StringIO(newline=b"\n")
<_io.StringIO object at 0x7f93d52953d0>
>>> import _pyio as pyio
>>> pyio.StringIO(newline=b"\n")
Traceback (most recent call last):
  ...
TypeError: illegal newline type: <class 'bytes'>

>>> io.StringIO([])
Traceback (most recent call last):
  ...
ValueError: initial_value must be str or None, not list
>>> pyio.StringIO([])
<_pyio.StringIO object at 0x7f93d4942610>
