New LaTeX OCR model; block visualizer; better links/references

Improved LaTeX OCR

We trained a new LaTeX OCR model that works a lot better overall. It will reliably output KaTeX-compatible math. It also operates on longer sequences than before.

The rendered output is on the right, original document on the left:

Block visualization

You can now visualize blocks in the streamlit app, thanks to @jazzido . By selecting json output and checking "show blocks", you get a nice visualization where you can see how marker parsed the page. Clicking on blocks will show the HTML.

Links and references

We fixed a bug with links and references, they now render as one block. You can see the extracted references here:

Misc bugfixes

• Fixed some bugs with tables and row splitting
• Escaped $ inside text and tables so we don't accidentally render things as equations
