Fix MSIXData _asdict AttributeError by using dataclasses.asdict (#459)

Replaces the incorrect _asdict() method call on MSIXData dataclass
with the proper dataclasses.asdict() function. MSIXData is a 
dataclass (not a namedtuple), so it doesn't have the _asdict() 
method that namedtuples provide.

Fixes #458 - resolves "'MSIXData' object has no attribute '_asdict'" error
