Bug

The default version string for megadetectorv6, megadetectorv6-mit, megadetectorv6-apache and megadetectorv6-distributed are incorrect raising a value error when loading without passing a string.

Fix is to update each string in the constructor to a valid version to match the if else statements

Minimal Reproducible Example

from PytorchWildlife.models import detection as pw_detection

# each call will fail
detection_model = pw_detection.MegaDetectorV6MIT(
    device="cuda",
    pretrained=True,
)
detection_model = pw_detection.MegaDetectorV6_Distributed(
    device="cuda",
    pretrained=True,
)
detection_model = pw_detection.MegaDetectorV6_Distributed(
    device="cuda",
    pretrained=True,
)
detection_model = pw_detection.MegaDetectorV6(
    device="cuda",
    pretrained=True,
)
