feat: adding type annotations to some constructor parameters

Using `get_typing_type` from `codegen/datatypes.py` to add Python
datatype to some constructor parameters.

Notes:

1.  Does not handle the `compound` datatype yet. `get_typing_type`
    raises a `ValueError` because it doesn't have a clause for this
    type; `add_constructor_params` catches this and simply doesn't add
    a type definition. Something between a third and half of all
    constructor parameters suffer from this, so we need to figure out
    what `compound` means and define a type for it.
2.  Almost all parameters are nullable, so the type is defined as
    (for example) `int` but the default value assigned is `None`.
