Make a page for uploading data to Nutrify

[mrdbourke]

Currently Nutrify is split into two apps:

1. The Streamlit app (for food image collecting) - https://share.streamlit.io/mrdbourke/nutrify/main/food_image_collector.py
2. The Nutrify.app homepage - https://nutrify.app

Long-term, this isn't sustainable.

So I'd like to merge them into a single app.

For example, you could go to https://nutrify.app/upload to upload an image of food/label it - perhaps the "/upload" could just link to the Streamlit app in the meantime?

The https://nutrify.app/upload would be a similar page to the main page, nice and simple.
