Allow projects to add observation fields offline

seems complicated. you would need some sort of mechanism to effectively download everything you would need for observation field input. if all your observation fields were just text input fields, that might not be so bad, but some observation fields are taxon-based. so you would need to download an entire taxonomy in those cases. i’m not developing the app, of course, but it just seems like too much complexity for a limited use case. in the meantime, you could just record everything in the observation nates and then translate those to observation fields later, right?
