Update __init__.py

Best practices to import with "*", also fixes my use case of automatically generate lookup dictionary by having the names of the models being exported:

from pretrainedmodels.models import __all__ as pretrained_models_names

pretrained_models_lookup = {
    name: getattr(importlib.import_module("pretrainedmodels.models"), name)
    for name in pretrained_models_names
}

lookup = {**pretrained_models_lookup}
