Donating training data

I'm planning on generating some amount of training data (hopefully on the order of 10s of thousands of pages, depends on cost) using [olmocr/data/buildsilver.py](olmocr/data/buildsilver.py) (at least I assume this is how the data was generated). I've been running this on a lot of medicinal chemistry-esque papers and its been struggling here.

If you are open to me donating the data, I can use open access papers exclusively for this, otherwise I'll just throw what I have into a private mix.
