Inline math; speed up LLM calls; allow local models

Inline math

Marker will handle inline math if --use_llm is set. This makes reading scientific papers a lot nicer! The feature has been optimized for speed.

Local LLMs

We now support Ollama - when you're passing the --use_llm flag, you can select the Ollama inference service like this:

marker_single FILEPATH --use_llm --llm_service marker.services.ollama.OllamaService

You can set the options --ollama_base_url and --ollama_model. By default, it will use llama3.2-vision.

Batch LLM calls

LLM calls are now batched across processors for a significant speedup if you're passing --use_llm.

Misc fixes

• Biology PDFs now work a lot better - leading line numbers are stripped
• Improved OCR heuristics
• Updated the examples
