Describe the feature or idea you want to propose

we would like to increase the use of type hints, and a good first issue is to add them for the simplest case when arguments are primitives (int, float, bool) or strings. Pick a package, look through the code and add type hints. Just for primitives for now, more complex types need a bit of thought. Many have npt.ArrayLike types, but we have not decided on standardising on that, so leave these alone. Dont feel you have to do them all, this is a good first issue to get you started.

Describe your proposed solution

for example, the constructor for the anomaly detection algorithm STRAY has these type hints

    def __init__(
        self,
        alpha: float = 0.01,
        k: int = 10,
        knn_algorithm: str = "brute",
        p: float = 0.5,
        size_threshold: int = 50,
        outlier_tail: str = "max",
    ):

but the segmentation algorithm CLASP does not

def _is_trivial_match(candidate, change_points, n_timepoints, exclusion_radius=0.05):
    """Check if a candidate change point is in close proximity to other change points.
