modify setup.py to correct installing hsdecomp

Hi, Thank you for making a nice tool.

However, I get the following error when I try to run hsdecomp after installing it:

$ python3 setup.py install
...
Using /usr/local/lib/python3.5/dist-packages
Finished processing dependencies for hsdecomp==0.1.0
$
$ hsdecomp
Traceback (most recent call last):
  File "/usr/local/bin/hsdecomp", line 11, in <module>
    load_entry_point('hsdecomp==0.1.0', 'console_scripts', 'hsdecomp')()
  File "/usr/local/lib/python3.5/dist-packages/pkg_resources/__init__.py", line 561, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)

    return ep.load()
  File "/usr/local/lib/python3.5/dist-packages/pkg_resources/__init__.py", line 2291, in load
    return self.resolve()
  File "/usr/local/lib/python3.5/dist-packages/pkg_resources/__init__.py", line 2297, in resolve
    module = __import__(self.module_name, fromlist=['__name__'], level=0)
  File "/usr/local/lib/python3.5/dist-packages/hsdecomp-0.1.0-py3.5.egg/hsdecomp/__init__.py", line 3, in <module>
  File "/usr/local/lib/python3.5/dist-packages/hsdecomp-0.1.0-py3.5.egg/hsdecomp/metadata.py", line 4, in <module>
ImportError: No module named 'hsdecomp.parse'

By debugging, I noticed that the contents of the parse folder inside the hsdecomp folder (subpackage) are not installed.

So I modified the code so that the package argument in the setup.py file contains the module 'hsdecomp.parse' like this:

Before:
packages = ['hsdecomp'],
After:
packages = ['hsdecomp', 'hsdecomp.parse'],

And i reinstalled hsdecomp and finally i can get hsdecomp.
