Bug: many foods not available to log in oz

This is an issue with many foods in the USDA database, particularly meats.

A couple examples are in Recipe #13622453 -- which also points out another problem here.

I cannot log this recipe in oz, only grams (unless I add a serving of 1 oz = 28g to the recipe).

I feel like any food item, whether recipe, custom food, or database food, that has a weight reference, should be loggable in either g or oz.

It should be easy enough to see if 'oz' is an option, and if it is not, but grams are, simply add it.
