Create a main.deepforest.set_label function

[bw4sz]

Most users won't know that you need to reset both the id -> class and class -> id dictionary.

m = main.deepforest()
m.load_model("weecology/deepforest-bird")
m.label_dict = {"Object":0}
m.numeric_to_label_dict = {0:"Object"}

we should have

m.set_labels({"Object":0})

that should reset both. If not m.evaluate will say the label is called "bird" from the loaded model weights.
