Using keyboard is creating unexpected errors inside the internal code of mcpi.

[xboxone08]

I am using keyboard for shortcuts. I have mapped the release of the key f5 to toggle the camera between setFollow(getPlayerEntityIds()[0]) and setNormal(getPlayerEntityIds()[0]). I also have a game loop processing block hits. It works fine a few times before either erroring out with:

Drained Data:  <b''>
Last Message: <events.block.hits()>
Traceback (most recent call last):
  File "foo_bar.py", line <irrelevant>, in <module>
    events = game.events.pollBlockHits()
  File "/usr/lib/python3/dist-packages/mcpi/minecraft.py", line 172, in pollBlockHits
    return [BlockEvent.Hit(*list(map(int, e.split(",")))) for e in events]
  File "/usr/lib/python3/dist-packages/mcpi/minecraft.py", line 172, in <listcomp>
    return [BlockEvent.Hit(*list(map(int, e.split(",")))) for e in events]
TypeError: Hit() missing 4 required positional arguments: 'y', 'z', 'face', and 'entityId'

I didn't right-click during the test
or

Drained Data: <b'525'>

This one might be fixed with #24
Note that game is the return value of mcpi.minecraft.Minecraft.create()

I did type that by hand at 1:00 AM, so a response would be appreciated.
