Added option for to use custom markers and color as well as custom annotations when plotting round

[JanEricNitschke]

In response to #133.

To reproduce the functionality from the issue one could use:

def annotations(
    a,
    map_name,
    frames,
    frame_index,
    annotation_args,
):
    for side in ["ct", "t"]:
        for p in frames[frame_index][side]["players"]:
            a.annotate(
                p["hp"],
                (
                    position_transform(map_name, p["x"], "x") - 15,
                    position_transform(map_name, p["y"], "y") - 20,
                ),
                fontsize=5,
                color="white",
            )
    return a


def players_markers(
    map_name, frames, frame_index, side, p, positions, colors, markers, custom_args
):
    player_names_colors = custom_args["colors"]
    if side == "ct":
        colors.append("cyan")
    else:
        colors.append("red")
    if p["hp"] == 0:
        markers.append("x")
    else:
        markers.append("o")

    pos = position_transform_all(map_name, (p["x"], p["y"], p["z"]))
    positions.append(pos)
    if p["name"] in player_names_colors.keys():
        markers.append(".")
        colors.append(player_names_colors[p["name"]])
    else:
        markers.append(".")
        if side == "t":
            colors.append("red")
        if side == "ct":
            colors.append("cyan")
    pos = position_transform_all(map_name, (p["x"], p["y"], p["z"]))
    positions.append(pos)

player_names_colors = {
    "brnz4n": "blue",
    "JOTA": "orange",
    "HEN1": "green",
    "Tuurtle": "yellow",
    "exit": "purple",
    "lux": "purple",
    "V$M": "orange",
    "felps": "blue",
    "Lucaozy": "yellow",
    "WOOD7": "green",
}

plot_round(
    filename=r"D:/CSGO/ML/csgoml/Plots/vis_improv/test_custom.gif",
    frames=data["gameRounds"][7]["frames"],
    map_name=data["mapName"],
    custom_marker_color_function=players_markers,
    custom_args={"colors": player_names_colors},
    annotation_function=annotations,
)

Should probably change the bomb marker to "1" like in the issue because otherwise it can be hidden by larger player markers (like here).

Also i am not really sure if the arguments that i am currently passing to the functions are the optimal ones. Maybe we can reduce them or maybe we have to add some (or also restructure them into a dict as well)
