Result.from_xml data argument has a wrong type doc

[wiktorn]

Passing Element as a data argument to Result.from_xml() as docstring suggests raises Exception.

>>> overpy.Result.from_xml(xml.etree.ElementTree.fromstring("<osm />"))
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/home/w/osm-borders/lib/python3.5/site-packages/overpy/__init__.py", line 310, in from_xml
    source = StringIO(data)
TypeError: initial_value must be str or None, not xml.etree.ElementTree.Element

It looks like it expects string right now:

>>> overpy.Result.from_xml("<osm />")
<overpy.Result object at 0x7faf632b2eb8>

My python version is:
$ python --version
Python 3.5.2

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.10
DISTRIB_CODENAME=yakkety
DISTRIB_DESCRIPTION="Ubuntu 16.10"

(My guess that Ubuntu's Python 3.5.2 is far more similar to Python 3.6 than to 3.5)

Thanks for reporting the issue.

I have merged a fix into the master branch. The fix will be in the next release.
