Detection label plot

[Gautzilla]

🏷️Supsupsup

This PR implements the feature of plotting detection labels next to the detection rectangles.

The usage looks like this:

detection.plot(
    ax=ax,
    detection_rect_kwargs={ # Keyword arguments passed to the detection Rectangle constructor
        "color": "#fde725",
        "linewidth": 7,
    },
    plot_label=True,
    label_kwargs={
        "anchor": "bottom_left",
        "inner_text": True,
        "text_kwargs": { # Keyword arguments passed to the label Text
            "color": "#440154",
            "size": "x-large"
        },
        "background_kwargs": {}, # Keyword arguments passed to the label background rectangle
    },
)

plt.show()

The anchor and inner_text parameter allow to place the label relative to the detection rectangle:

There are 8 possible combinations. In the notation x_y_z above, x_y represents the anchor (T_R stands for "top_right") and z represents the inner_text parameter (I for True (inner), O for False (outer)).

Resolves #433
