Misc fixed to Streamlit demo

[osanseviero]

Hello!

I built a Space demo hosting your Streamlit example (link at https://huggingface.co/spaces/osanseviero/doctr). It works great and is much faster than I expected.

I did face some issues during the development. I hope this PR fixes them:

1. You suggest to install doctr in the requirements but I think that's actually an unrelated package, it should be python-doctr.
2. But then out.pages[0].synthesize() threw an error saying Page class has no synthesize method. This was introduced in feat: Improved font resolution and page synthesis #472 so I don't think it's in the recent release.

Given 1 and 2, and that #472 will probably be soon in a release, maybe we could change requirements.txt to install python-doctr[tf] instead of installing directly from GitHub. WDYT?

Thanks a lot for the demo & the bug fix @osanseviero 🙏

To answer your questions:

• we have an upcoming release in a few days so the page synthesis will be on a stable release!
• you're correct about the package ref in the demo, but for the same reason than your first point, I think it might be best to stay aligned with the main branch on Github, don't you think?

I added a comment to use the extras to have a fully compatible TF environment, let me know what you think!

Thanks for your input! I changed the requirements as you suggested and removed the TF requirements since they are part of the extras.

I'm glad you liked the demo!

Much appreciated Omar!

@osanseviero by any chance, is there a markdown badge or something similar for huggingface spaces demo?
That could be a cool thing to include in the README in another PR 😁
