[feature idea] File upload

[99hats]

Cool project!

I realize this is probably out of scope, but it's critical for line of business apps where the data doesn't live on the server your running from. I can see use cases for line of business and ai applications that fits somewhere between gradio/h2o and streamlit/nicegui/reflex.

I'm currently using NiceGui for my line of business projects because it's the only python forward framework that has robust file upload that can not only handle large files but provide feedback on the upload process.

In the meantime, I'm working on embedding textual into my existing project.

Kudos and all of your amazing projects.
