keys are not trimmed

Version: 0.4.2
OS: OSX (but irrelevant)

I came across this issue when attempting to render a cookiecutter template from a user config
where there was a space between a key and the colon.

While this is very trivial, it is hard to root cause because the error message is something like
Error message: 'dict object' has no attribute 'python_3_6' and only careful examination of the dumped structure shows the problem

"interpreter_versions": {
            "python_2_7": "no",
            "python_3_5": "no",
            "python_3_6 ": "yes",
            "python_3_7": "yes"
        },

How to reproduce

If you take this (valid) YAML example and parse it through poyo

python_3_6 : yes

you get (note the space after the python_3_6 key

>>> from poyo import parse_string
>>> config = parse_string("python_3_6 : yes")
>>> config
{'python_3_6 ': 'yes'}

whereas it should have been {'python_3_6': 'yes'}
