Fix comment in types.py to match the code
Fix comment in types.py to match the code

The comment says that the key should be `_analysis` but in the code it is `analysis`: https://github.com/foosel/OctoPrint/blob/master/src/octoprint/slicing/__init__.py#L312

This fixes the comment but leaves the code unchanged.
