Add type hints to type-specific lists

[nathan-hess]

Major Changes and Improvements

• Set up type hints for pyxx.arrays.TypedList and pyxx.arrays.TypedListWithID

This aids in type-checking:

from pyxx.arrays import TypedList
myList = TypedList(list_type=float)
myList.insert(0, 'newValue')

# Generates Mypy warning:
# Argument 2 to "insert" of "TypedList" has incompatible type "str"; expected "float"

It also allows more useful auto-completion:
