Missing feature metadata when loading model

[Ethan-Earlie]

When loading a trained model I ran into an error of trying to concat an empty dataframe when reading the features metadata.

This is because there was features metadata for the first view, but not subsequent views.

To fix this for future users, I recommend changing line 74 in mofax/utils.py from:

if len(list(model.model["features_metadata"][model.views[0]].keys())) > 0:

To:

if np.all([len(model.model["features_metadata"][v].keys())>0 for v in model.views]):

THANK YOU SO MUCH! This saved me from needing to retrain for half a day again.
